This is a sleeve for the limited-edition three-box set of "Gin-dako" takoyaki in collaboration with "Demon Slayer," featuring a three-bean cheese chili con carne flavor, along with a limited-edition collaboration card of Inosuke Hashibira. I obtained these today and have stored the card in a bag after taking photos. There are no noticeable scratches or stains. Would these be suitable for a collection or for use in handmade crafts?
