Hi everyone!! So I just found the link to kouri's shop where he sells Ib merch! (the site is in Japanese u0u)
It's here!! : [link]
Apparently he also recently added some new items like a B5 notebook with Ib character print, and a case that comes with an Ib card!!
As well as that, Movic now has some new items in store again, like keychains, tote bags and posters!!
Here!! : [link]
Quickly, before it all goes out of stock again guys!! *q*
