A case that holds together few Japanese traditions and reinvents them: made of re-invented washi paper, named a national treasure, folded like an origami, this case represents eight generations of family knowledge and skill. It folds extremely flat when empty but the pockets pop open to encase the thickness of about 16 credit cards. Also holds folded cash and coins. Cotton fabric lining added to inside pockets for durability. Handmade in Tokushima, Japan.
