Tri-fold sleeve

Abstract

This product is designed to protect cards used in board games and card games. Cards can gradually become damaged, peeling, scratched, bent, wet, or dirty, but using a sleeve will keep your cards in pristine condition. Furthermore, by changing the size, it can accommodate various tri-fold products such as business cards and brochures. While there haven't been any sleeves to protect cards that can be folded before, it's likely that a shape that can accommodate special products will be desired in the future.
