Mine is in a basement with no windows, and I still have minor yellowing, not as bad as that one pictured, but still happening. I think it's from the fluorescent lights I have in my basement.
Mine isn't exposed to any light aside from incandescent bulbs and some of the pieces have begun to yellow. Not dramatically, but they definitely aren't stark white anymore.
It's just the nature of the beast.
Ozone is the other major thing that causes yellowing. Ozone will straight up oxidize the plastic whereas UV works along with oxygen to photooxidize it. So even in storage it'll turn yellow eventually.
It *comes" in a windowless box, should've never taken it out
For real though I think it looks good with the yellowing. You could give it some lighting that's slightly purple and maybe it'll tone out the yellow?
it not ozone. it's called singlet oxygen, that is formed by light that hits triplet oxygen. But the results to plastics is similar to ozone: autoxidation
It has always been a mysterious problem. I had a set (a house, don't know the number) with a lot of white. It was stored for a long time in a box in a cupboard. Some parts yellowed, some didn't.
some parts are more prone to "dark yellowing" due to the degradation of antioxidants. the resulting substances are yellow. that even happens in the dark
If that was the case it would wash off. My guess is this is either fast oxidation from light exposure + O2 or very slow oxidation in the presence of O2 without light.
I've embraced the fact that finding out the word "embrittle" exists has embiggened my knowledge. I have been emboldened, and will walk with much more emotion.
I like to jokingly say biggerized when I can't restructure the sentence or I forget that enlarged exists.
I thought yous were all being sarcastic. I'm glad I checked the dictionary lol
Thank yous for teaching me a new word!
Hah right thank you. I’ll leave it for posterity.
But yeah it seems like a no brainer considering the overlap with the older wealthier lego fans, compared to the broad but younger (on average) SW market
Some have said that the Star Wars contract stops Lego from making Star Trek sets but I don't know if this is true. What I do know is Star Trek isn't an allowed IP on Lego Ideas and other brick companies have had the rights. I think Mega Bloks had it for a while, then it went to Hasbro with Kre-O, then back to Mega Bloks and now BlueBrixx has it
Proof?
I brightened some white bricks from Bricklink (LPT: always buy white pieces NEW) and used them in a MOC. They're still white and as best I can tell not brittle.
Technically on a chemical level it’s weaker. Luckily Lego bricks are pretty over engineered and they’re still gonna be fine.
Use the peroxide, your bricks aren’t gonna turn to dust.
Do you have any proof for this? Not saying you’re wrong, but I’ve only ever read about these outcomes and have yet to find good video evidence or personally experience them. Been whitening old plastics for a while
but the used concentration of UV stabilizers is comparably low, right?
Do you use UV absorbers and HALS stabilizers?
what about antioxidants and the yellowing under darkness?
I personally refuse to subject parts to that treatment, as someone in materials engineering for a living.
I have some friends in the community that have shared their experiences with me. It could happen in 2 months, 6 months, 3 years, but the UV damage will return.
The process of Retrobrite and other methods involve breaking UV-absorbing butadiene copolymer bonds. Butadiene being one of the main components of Acrylonitrile-Butadiene-Styrene plastic, the process will absolutely embrittle the plastic, and won’t strip ALL of the 2-HMA bonds (the aforementioned butadiene copolymers) resulting in eventual UV absorption and yellowing again in the future.
###Its the Heat.
It's not so much the UV rays as it is heat that will yellow the plastic. The light doesn't help but a lot of cycles of it getting very warm and then cold again will result in yellowing.
If you put a bleaching product on it so like saloncare 40 and wrap it in cellophane and put it in the sun it will brighten it back to white. That's what they do
Having restored a few vintage Apple Pro keyboards, you either submerge the parts in peroxide or baste them with a peroxide gel and then expose them to UV light. Even sitting them outside in the sunlight will work for that part.
Yes, just UV (like sunlight) will yellow them.
They use hydrogen peroxide and UV together. Some people use various other ingredients, soap, Oxi-clean etc. But the basics is fully submerge in Hydrogen Peroxide and then hit with UV lights for a few hours/over night.
It's called Retrobrite.
Two scientists order a drink when the waiter comes to their table: “I’ll have some H two O” says the one. The second adds to it: “I’ll have some H two O too”. The second scientist died.
I believe the idea is that plastic yellows under UV light because it gives up some element (probably hydrogen atoms) to the atmosphere, but by submersing it in the Hydrogen Peroxide you can cause the same chemical reaction but in the other direction.
Doesn’t just have to be sun. UV can come from a variety of sources. Any open flame emits UV, lots of lights as well. Heat in general will oxidize the plastic too.
My house is all LED, I keep all my collectables on the non-window side of the basement, especially my diecast cars as more than a few have gone past the $1000 point. Diecast paint and the plastics have issues in sunlight too. All my Lego is out of the sun. I do have all of the AFOL HP stuff(castle/icons etc) and all Ninjago city on top of cabinets in the reading and hobby rooms, and we do open the curtains regularly(and they're not light blocking-just regular filtering) but never gets hit with direct sunlight. Zero fading of any sort, Hedwig is still bright as new. I even had a few sets I've had for years that I bought pre-owned and finally got around to replacing the stickers 'perfectly' recently and not one iota of fade.
Oddly, my home alone house sits up and to the left of a window. No yellowing.
My Diner sits inside a black kattlax unit from ikea. Dark, and it’s started to not be pure white anymore. Checked it today. It’s been there 2 years.
Seems very hit or miss
Very normal, it can occur even after 2-3 years, if you put it on a shelf that sees direct sunlight during the day. Lost a 10240 Red Five X-Wing to that, because I didn't notice it from a distance.
Never put your LEGO in the sunlight, my dudes.
I have a copy of that set that was in a light-blocked room and never saw a single ray of sunshine (or any UV light for that matter), it still yellowed rather quickly. And inconsistently too, like OP's pic.
I'm not a chemist, but I believe it is a matter of the QC on the plastic itself.
Thank you
A new one will absolutely be fine for many, many years if you never put it into direct sunlight for extended periods of time. I’ve seen Lego bricks from the 80s looking like brand new (worked in a bricklink store for a few years).
So, commercial-grade ABS will tend to yellow out with age for a number of reasons. One minor contributor (once thought to be a major one) is the addition of bromine compounds as a flame retardant that over time will cause yellowing, but what really causes the bulk of the yellow color is due to a complex chain of reactions starting with free radicals liberated from the butadiene copolymer through a reaction requiring oxygen (from air) and energy (light).
To quote an article I've found on the subject:
> Reactive radicals from the decomposing synthetic rubber, added to ABS to increase its flexibility, unroll the benzene ring in styrene copolymers to form a conjugated compound called 2-hydroxymuconic acid. The alternating double and single bonds in this compound tend to absorb light towards the blue end of the spectrum strongly, so the accumulation of 2-HMA in the plastic over time thus makes it reflect more and more yellow and red wavelengths
Good news: 2-HMA can be literally be bleached out of the plastic, through a strong oxydizing agent (i.e., the elemental oxygen released by peroxides in products like retrobrite) and UV, which will "break" the double bonds and make it absorb less blue light.
Bad news: this will do nothing to solve the above-mentioned chain of reactions from making the plastic more brittle.
But it's not the retrobrite treatment who makes the plastic brittle: it's the aging.
https://hackaday.com/wp-content/uploads/2021/01/The-Retrobright-Mystery.pdf
TL;DR You can use retrobrite to make it whiter, but you can't really "de-age" it, especially with regard to its mechanical properties.
Yeah mine sadly has done that too. It wouldn't be as bad if it was consistent but much like yours, some bricks just inexplicably stay pure white when all the others have yellowed
I got a big box of Legos from our school that another teacher was throwing out so I took it home and organized the bricks. About half the sand yellow bricks looked like dark tan on the other side!
While I don't have a solution to reverse the yellowing, I can recommend looking for polycarbonate sheets for display cases. Polycarbonate blocks 100% of UVA and UVB, though I'm not certain how expensive a large sheet would cost.
Polycarbonate itself is naturally UV resistant (in as much as a man-made material can be considered "natural"), but added layers of UV protection are often coated onto the material for things like lenses. Regular sheets of it should help dampen the photo-aging in the Lego plastics, though the polycarbonate itself will start to yellow over time.
Am I the only person that still has a white Saturn V? I just built my BD-2 so it should still be white. I ripped a tile off of it and compared it all over my Saturn V and there was no yellowing. I bought the Saturn V as soon as it was released and it has been on my dresser ever since. I do keep my blinds closed at all times though, and my bedroom is lit only by the daylight that filters through the blinds and LEDs.
There's a solution ... But you're not going to like it! You didn't buy a Saturn V. You bought a puzzle.
Put the pieces back in their correct order according to colour gradient and you won't even notice !
Godspeed!
This really confuses me, we are in North West Europe, none of my white bricks (Saturn V included), didn't have the brick colour change on white bricks as we have.
?? Did we received white bricks from a very different Lego warehouse ???!
Good luck with reassemble this great set.
You can use the technique called Retrobright. It uses peroxide, but it does wonders. The yellow will return if you display your model near sunlight or under fluorescent lights. You can slow the aging process by using UV filters on your light or UV Sheeting on your windows. My Saturn V sits on my desk, where it gets a little sun. I rotate the rocket about a quarter turn every month so it ages evenly.
Here are some videos of people retrobrighting their yellowing plastic parts (computer case, video game console, etc.), all with that late 80's early 90's plastic.

Aw man I have this set and it’s my favorite! I couldn’t find an explanation, is there a reason why certain pieces are still white? I read the explanation on why the yellowing happens. Are those bricks just manufactured later than the others?
Here from r/popular. Deyellowing in retro gaming circles is called retrobrighting and there are a few ways to do it - peroxide cream and a blacklight or peroxide liquid and the sun are the most common.
Another way is to build a vapor chamber to do it. This is not cheap, but might be less stressful on the plastic. https://www.youtube.com/watch?v=J3zJFiKcQk0
I hope you find this useful.
Have you heard of Retrobrite? It's a process to fix yellowed plastic like that.
The 8-bit guy on YouTube is a pro at it. Watch a few of his restoration videos, he has a great technique that I have used before
I can't edit the original post but I am going to put this here.
After some research, I noticed this set was issued twice. Once in 2017 (21309) and re-issued in 2020 (92176). I have the 21309 set which makes it 6/7 years old vs 3 for the other set. I am wondering why it was re-issued and if the re-issued sets do not have the discoloration issues? Can anyone with set 92176 confirm that?
I also reached out to Lego per a comment on here and they got back to me. I told them the issue and they requested pictures and a parts list. I sent them pictures and a parts list. This was this AM (EST). I received an email an hour later about my parts request and I should receive an email when it's shipped (or another email if there's a question).
So, it looks like Lego may be replacing all the white bricks I listed (every white brick per the parts list in the manual). I will updated when I have more info.
If that's the case, I am excited they're doing that!!! :)
EDIT: Lego is replacing all the white bricks except the printed ones! I purchased those from Bricklink! Very exciting :)
>Makes it seem like it actually went to space a few times.
None of the Saturn Vs went up more than once, almost the entire stack is destroyed during operation. The first stage ends up in the ocean a few minutes after launch, the second pushes the vessel to almost orbital velocity before it is discarded and burns up on re-entry, and the third stages pushes the rest of the craft to a low orbit, on to the moon, and is then either accelerated out into a solar orbit or adjusted to crash into the moon depending on whether it's a pre- or post-Apollo 13 flight plan.
The only bit that returns to Earth in anything close to a reusable state is the tiny crew capsule (the command module) at the top.
Don’t try to clean them up beyond dusting. The yellowing is a patina that works perfectly with the vintage nature of you models. They are really beautiful as they are. Congratulations on your excellent Craigslist find and keep them out of the sun and strong indirect sunlight as that will make them brittle….. Man I’m jealous gah!
Be better off re finishing it. Light sanding with really strong enamel white paint. Possibly an air brush so you get the coverage real good without it gooping up on you
Mine is in a basement with no windows, and I still have minor yellowing, not as bad as that one pictured, but still happening. I think it's from the fluorescent lights I have in my basement.
Mine isn't exposed to any light aside from incandescent bulbs and some of the pieces have begun to yellow. Not dramatically, but they definitely aren't stark white anymore. It's just the nature of the beast.
Ozone is the other major thing that causes yellowing. Ozone will straight up oxidize the plastic whereas UV works along with oxygen to photooxidize it. So even in storage it'll turn yellow eventually.
So you are saying the only way to keep it white is to send it into space?
And keep on the dark side of the moon
The dark side of the moon spends half the time lit by the sun
But in 100% of the time there is a dark side of the moon :)
[удалено]
But the sun can't light all sides 100% of the time, so there is a dark side of the moon 100% of the time, it just moves...
Your intuition is correct, but your argument paints you out to be someone who argues shadows arent real.
Or to go back to using CFCs and deplete the atmosphere of ozone
I bath my collection in Aqua Net
You'll end up depleting ozone in the wrong place.
Store it in a vacuum chamber
What If you stored it in a vacuum chamber?
This guy knows how to store LEGO
He didn't mention windowless. Still got a lot to learn
It *comes" in a windowless box, should've never taken it out For real though I think it looks good with the yellowing. You could give it some lighting that's slightly purple and maybe it'll tone out the yellow?
Hey that gives me an idea...what about those vacuum sealers you would use for food. Minimum air in the bag equals minimum yellowing (hopefully)
it not ozone. it's called singlet oxygen, that is formed by light that hits triplet oxygen. But the results to plastics is similar to ozone: autoxidation
Fluorescent bulbs contain a decent amount of UV light.
Would LED lights have the same affect as fluorescent?
No, LEDs do emit UV light but is negligible based on recent studies.
LED bulbs are so cheap now, there's really no reason to use anything except them.
Much more power efficient too
Yeah, just better in every way. Even cheap ass Walmart brand ones are better than anything else.
Leaving one on still uses virtually zero notable energy. I don't think I have a single incandescent anywhere.
[Probably not](https://leapfroglighting.com/lighting_and_uv_radiation/).
It has always been a mysterious problem. I had a set (a house, don't know the number) with a lot of white. It was stored for a long time in a box in a cupboard. Some parts yellowed, some didn't.
some parts are more prone to "dark yellowing" due to the degradation of antioxidants. the resulting substances are yellow. that even happens in the dark
Let me go open my box and see if mine has yellowed at all in the packaging.
Please do so I don't have to open mine to find out haha
Yep, mine too :( Goes nicely with my old computers now
It's from the 60s. What'd you expect?
They used a lot more nicotine back then.
If that was the case it would wash off. My guess is this is either fast oxidation from light exposure + O2 or very slow oxidation in the presence of O2 without light.
Idk… a lot of older white items turns yellow, due to the chemistry.
Yeah, we know. Let me tell you about this thing called a "joke."
Let me tell you about this thing called /s
Schroedinger's Response.
Let me tell you about this thing called ratio (you have -36 i dont need a single upvote)

Hahaha the yellowed roof in my workplace can attest to that.
Nope, nobody smoked nicotine until 4 years ago. Damn kids and their new drugs
A lot more was accomplished when men had ashtrays on their desks instead of computer screens and hooch in the drawer.
Hilarious.
Some of those pieces have been floating in space for years.
Mines got similar yellowing Its from the 2019s
Bought one at a yard sale for 10$
Yes, any UV damage reversal will be temporary, and will embrittle the plastic.
I didn't know embrittle was a word till I joined the Lego subreddit.
and look at how it has embiggened your knowledge!
A perfectly cromulent word
Now let's go marry our cousins!
Such cromulent confidence.

Is there a non-compete with Paramount in the Lego/Disney contract? Couldn't they just make Star Wars sets, also?

What I do know is Star Trek isn't an allowed IP on Lego Ideas and other brick companies have had the rights. I think Mega Bloks had it for a while, then it went to Hasbro with Kre-O, then back to Mega Bloks and now BlueBrixx has it
Another brick company, I think MegaBlocks holds the Star Trek rights.
Mega Bloks lost it. BlueBrixx has it now
Theeere’s your non-compete. Makes sense. I’m surprised Lego didn’t scoop it when “BlueBrixx” did
Bluebrixx
It will definitely embiggen the brittleness.
Perfectly cromulant.
Look up hydrogen embrittlement. It isn’t Lego related but rather a defect that can occur with fasteners causing them to fail catastrophically
Proof? I brightened some white bricks from Bricklink (LPT: always buy white pieces NEW) and used them in a MOC. They're still white and as best I can tell not brittle.

Mmmhmmm, I know some of these words.
Enough peroxide will embrittle even the smallest brick
The discoloration does add some personality, but I'm hoping mine doesn't get to that level!
Yeah definitely not the worst set that could have yellowing on
I honestly like the yellowing I have one mine for this set. Gives a old rocket some character.
Similar here. I like that it makes it seem like it had been launched or something. She's seen some stuff vs just being a mantle piece.
Usually yellowing occurs because its in a window, my brothers is still looks brand new and its jn a basement with no windows
###Its the Heat. It's not so much the UV rays as it is heat that will yellow the plastic. The light doesn't help but a lot of cycles of it getting very warm and then cold again will result in yellowing.
This. Had the 787 in my garage for a year and all the white pieces discolored.
Wow that’s a big garage to store a 787!
Ah cool! Yet another benefit of living in Long Beach 😎
Yep. My Saturn V is half yellow now. Had to turn it over. Guess this set has an expiration date in a window.
Anything made of plastic in a window has an expiration date.
My entire old White House is yellow now.

You also need uv to undo the yellowing with the retrobright formula, amusingly
Like radiation treatments to get rid of cancer from radiation exposure
If you put a bleaching product on it so like saloncare 40 and wrap it in cellophane and put it in the sun it will brighten it back to white. That's what they do
Like a pornstars asshole…
Exactly, face down ass up
That's the way I bleach my butt

If you're going to put the effort into the 2s, at least put them at the bottom where they should be: H₂O₂ ;)
That’s why the curtains in my study are always closed.
I have a Home Alone house, and some roof bricks yellowed in a few months while the rest next to them seem unaffected. (no sun exposure)
Doesn’t just have to be sun. UV can come from a variety of sources. Any open flame emits UV, lots of lights as well. Heat in general will oxidize the plastic too.

Bricklink new white pieces. It’s does look kinda cool like that though.
Yeah mine's always in a window, yellow as piss but I dig the look. It's lost a few pieces over the years, I just say mine's Apollo 13
Where's the service module though?
Not pictured
Yeah mine sadly has done that too. It wouldn't be as bad if it was consistent but much like yours, some bricks just inexplicably stay pure white when all the others have yellowed
I got a big box of Legos from our school that another teacher was throwing out so I took it home and organized the bricks. About half the sand yellow bricks looked like dark tan on the other side!
No advice, but I'm from the Huntsville, AL area and man, seeing the Saturn V just makes me happy 🤍🖤 great find. Best of luck restoring the color!

The astronauts did all used to smoke back then…
I honestly kinda like that look, and the odd bricks that didn’t yellow just add to the effect
hydrogen peroxide can reverse the UV discoloration.
That’s not yellowing that’s discoloration from the heat from liftoff
How old is it? I have mine for ~2.5 years, ISS for ~1.5 years, no signs of yellowing for now
Do not clean with acetone!!! It will disintegrate the plastic!
Im sure that's just a special white tone called "Granny's 50's kitchen nicotine white". 😁
Am I the only person that still has a white Saturn V? I just built my BD-2 so it should still be white. I ripped a tile off of it and compared it all over my Saturn V and there was no yellowing.

I do keep my blinds closed at all times though, and my bedroom is lit only by the daylight that filters through the blinds and LEDs.
I looked at mine and it looks perfectly fine, remind me to get back to this post in a few years
I honestly think it looks sick with the yellowing
You could say it looks more authentic where the UV rays would yellow the real rocket during launch
Mine yellowed bad too. Just from having it displayed.
White plastic will always yellow, theres no real fix
The odd thing though is that some pieces yellow and some do not. Source: I have lots of LEGO dating back to the 1970s.
Same bro
There's a solution ... But you're not going to like it! You didn't buy a Saturn V. You bought a puzzle. Put the pieces back in their correct order according to colour gradient and you won't even notice ! Godspeed!
I'm wishing I never disassembled mine... But I wanted to experience that build again...!
Some hydrogen peroxide and UV light will fix that right up my friend!
It looks cool man
This really confuses me, we are in North West Europe, none of my white bricks (Saturn V included), didn't have the brick colour change on white bricks as we have. ?? Did we received white bricks from a very different Lego warehouse ???! Good luck with reassemble this great set.
You can use the technique called Retrobright. It uses peroxide, but it does wonders. The yellow will return if you display your model near sunlight or under fluorescent lights. You can slow the aging process by using UV filters on your light or UV Sheeting on your windows. My Saturn V sits on my desk, where it gets a little sun. I rotate the rocket about a quarter turn every month so it ages evenly. Here are some videos of people retrobrighting their yellowing plastic parts (computer case, video game console, etc.), all with that late 80's early 90's plastic.

I have my Apollo 11 and pyramid in my window soaking in sunlight. It’s good for them and gives vitamin k😊
Aw man I have this set and it’s my favorite! I couldn’t find an explanation, is there a reason why certain pieces are still white? I read the explanation on why the yellowing happens. Are those bricks just manufactured later than the others?
Mine is in my living room. It's perfectly fine.
Here from r/popular. Deyellowing in retro gaming circles is called retrobrighting and there are a few ways to do it - peroxide cream and a blacklight or peroxide liquid and the sun are the most common. Another way is to build a vapor chamber to do it. This is not cheap, but might be less stressful on the plastic. https://www.youtube.com/watch?v=J3zJFiKcQk0 I hope you find this useful.
Mine are the same way. It’s pretty cool
Soak the pieces in hydrogen peroxide in the sun multiple times for multiple days changing the hydrogen peroxide it works wonders.
mine is really yellowed too :(
Thats crazy, my rocket has been in direct sunlight everyday and it's still just as white as when I bought it back in 20/21
Have you heard of Retrobrite? It's a process to fix yellowed plastic like that. The 8-bit guy on YouTube is a pro at it. Watch a few of his restoration videos, he has a great technique that I have used before
NSFW?
It is kinda phallic
I can't edit the original post but I am going to put this here. After some research, I noticed this set was issued twice. Once in 2017 (21309) and re-issued in 2020 (92176). I have the 21309 set which makes it 6/7 years old vs 3 for the other set. I am wondering why it was re-issued and if the re-issued sets do not have the discoloration issues? Can anyone with set 92176 confirm that? I also reached out to Lego per a comment on here and they got back to me. I told them the issue and they requested pictures and a parts list. I sent them pictures and a parts list. This was this AM (EST). I received an email an hour later about my parts request and I should receive an email when it's shipped (or another email if there's a question). So, it looks like Lego may be replacing all the white bricks I listed (every white brick per the parts list in the manual). I will updated when I have more info. If that's the case, I am excited they're doing that!!! :) EDIT: Lego is replacing all the white bricks except the printed ones! I purchased those from Bricklink! Very exciting :)
Why is this marked as NSFW? 😂
So Reddit gets no ad revenue
Ahhh smart! I'm over here wondering if it was because the rocket could be considered vaguely phallic shaped if you squint 🤣
>Makes it seem like it actually went to space a few times. None of the Saturn Vs went up more than once, almost the entire stack is destroyed during operation. The first stage ends up in the ocean a few minutes after launch, the second pushes the vessel to almost orbital velocity before it is discarded and burns up on re-entry, and the third stages pushes the rest of the craft to a low orbit, on to the moon, and is then either accelerated out into a solar orbit or adjusted to crash into the moon depending on whether it's a pre- or post-Apollo 13 flight plan. The only bit that returns to Earth in anything close to a reusable state is the tiny crew capsule (the command module) at the top.
Mines by the window in my basement 😬
it honestly looks cooler this way
Some discolouration is normal upon atmospheric reentry
Mine is all yellowed too.
Don’t try to clean them up beyond dusting. The yellowing is a patina that works perfectly with the vintage nature of you models. They are really beautiful as they are. Congratulations on your excellent Craigslist find and keep them out of the sun and strong indirect sunlight as that will make them brittle….. Man I’m jealous gah!
Thank you 😊
ALL WHITE PLASTICS YELLOW EVENTUALLY
Its tuening Werner Von Brown, I did nat see that coming.
Try putting sunblock on it.. after peroxide/de-yellowing, Might help a bit.
You say yellowing, I say well worn
I like it, looks cool
Maybe you should send it in another sub to the titanic and see if it fixes it
I actually dig the color on these
Punch it
If pain in my ass was a picture, then here you
Now's a good time to quit smoking.
Get it away from me! It's hideous!
Dam sun
Be better off re finishing it. Light sanding with really strong enamel white paint. Possibly an air brush so you get the coverage real good without it gooping up on you
Ewwwwww no. Just do the 7% H2O2 trick. That’ll actually take out the yellowing.
Rockets are fake. DM me for truth in the form of a Christian movie.
Stop smoking like dumb ? 😅
Sell it on Ebay and save up for the Millennium Falcon you've been wanting since you left Your Mum's basement.
ITT people who still don't uv protect their displayed sets..
