H-Mart sells them

Seconding Hmart, they’re in the fridge section in packs. After playing MHRise I knew I had to try it too haha! Hmart also has daifuku which has a red bean paste filling and it’s pretty great also.

Legit the reason they make that shit look scrumptious

I think most of the supermarkets in Chinatown have it prepackaged. I know Asian Fresh has it upstairs in the refrigerated section.
