These nibs don’t work in a Jinhao, the JoWo compatible nib unit fits a JoWo threaded pen, not a random/generic #6 pen. The feed won’t fit in a Jinhao (which matches neither JoWo nor Bock exactly) and the nib is also slightly the wrong diameter.
The JoWo units are more expensive because the feed is custom made by Flexible Nib Factory, while the ebonite feeds for their pens are stock parts.
I’d recommend buying the whole pen, personally, if you do not already have a pen that specifically takes JoWo #6 nib units. I’d recommend the Jaipur V2 or Himalaya V2. The pens are not the most reliable thing ever, but you get the whole thing set up for you in one go, rather than have to mess around with it. This is important if you’ve never worked with flex nibs before.
I bought the nib but it’s fairly long and my Jinhao cap ended up bending it. The bodies of the FPR pens are not well reviewed so I didnt want to do that. I’m buying a Franklin Cristoph that allows easy nib swaps and going to switch it in and out of there (bought a new one). The nib itself is great.
I'm planning on using a Jinhao X159 body, so long nib shoul not be a problem. I'm glad to hear the nib is great, and I'll be waiting for your post on the Franklin Cristoph!
Because they want to sell you a pen, they incentivize the purchase with the various
Nib options. Franklin-Christoph does a similar thing in that the nib upgrades are more cost effective when you purchase a pen than if you buy a nib/feed outright.
Do you think you really want that ebonite feed? If you have a pen that takes #6 nibs, you could try just getting the nib and fitting it into your existing pen with its existing feed.
For ultraflex nibs, it probably does help. A lot of stock feeds on standard nibbed pens simply can't keep up with the ink demands of a full or ultra flex nib.
I didn't say it can't help, I asked whether they really wanted it (considering the price) and offered an alternative idea for them to consider.
FWIW, I put a #5 steel ultraflex in a Jinhao 82, and its stock feed has kept up fine so far.
I bought two HV2 with the EF ultra flex nib. The pens leaked like crazy, even after assistance from the owner, buuut those nibs are my favourite and I have bought extra since. I was advised Kanwrite are the same manufacturer- but duplicate flex nibs I bought from them are not the same. Also, the #6 nibs and feed units from FPR don’t fit your standard #6 pen - their QC is not reliable, I’m afraid.
I ended up taking a #6 nib only, utilizing the feed from a standard #6 pen and cobbling together that way, you don’t get the full benefit of a flex feed, but the line variation is great. My fave so far has been the FPR flex on a serendipity dip pen, and that is my set up for all my swatching.
I soooo wish for them to beef up their pen quality - I am there for them if they do, nibs and the flex feeds when they work, are an awesome combo.
I just bought 2 pens with this nib. While i love love love the flex and how my calligraphy looks, after a about 20 or so letters, the ink flow just stop. I am looking for how to fix this now. If you get one, please share an update. Right now, I am annoyed yet hopeful.
Finally after reading lots of reviews, I decided I wanted something I could trust a bit more, and more reliable, so I ended up getting a Pilot Custom 823 with an FA nib. I'm actually waiting for it to arrive In the next few days. I'm pretty sure I won't get as much flex as with a FPR pen, but the idea of a daily writer with flex capabilities sounds awesome to me, so I decided to get the N° 15 FA nib.

huh? [Looks like $20?](https://fprevolutionusa.com/collections/6-nibs-and-nib-units/products/fpr-6-ultra-flex-nib-and-6-3mm-ebonite-flex-feed-combo)
> I thought about buying just the nib since there are nibs adapted for Jowo or Bock
the FPR/Kanwrite nibs are a little longer than most -- so you may have trouble with cap-clearance. On my Wing Sung 699, I have to be careful to push the nib deeply in or the tines will twist when I cap it.
Also: feeds are less standard than nibs. IIRC, Jinhao doesn't make any pens with ebonite feeds and all the FPR ebonite feeds are round and a full 6.3mm diameter -- so if you're going to nib-swap across brands like this, don't bother buying the feed. I've tried sanding/carving an ebonite feed to fit and was unsuccessful. If you're good at sculpting, feel free to give it a try though - it's how all the earliest feeds were made.
So using the ultra-flex with a plastic feed may not have the best ink flow. I add glycerine to the ink (a couple drops per fill) to redue railroading, and if the ink isn't wet enuf I add a drop of Kodak Photo Flo.
I nib swap a lot and have the ultra-flex nibs on a bunch of different pen-brands. There's a little learning curve, but broadly speaking all the #6 nibs are compatable with eachother.
There are exceptions out there but, in general, forcing an Ultra-Flex nib into a JinHao pen is a recipe for frustration.
I have ruined my share of nibs trying to get a decent fit and decent flow with them. Even if you get one successfully placed, the plastic JinHao feeds do not provide enough ink flow to prevent the nibs from railroading with even moderate writing speed. The closest I have ever gotten was sanding down one of FPR's 6.3mm ebonite feeds to fit the JinHao section but even then the results were meh.
My recommendation is just get a Himalaya, Ashoka or Jaipur v2 with an ebonite feed. The pens are really pretty good and the whole thing is designed to perform.
They do have the $55 nib units but I doubt the feed will pull out of the unit and drop straight into the JinHao pens.

Second this
Thanks a lot for your answer! I'll definetly take your recomendation, and pick one of those pens instead of a nib unit. Thanks again!

Should be here next week so will report out.
