This is a flat, handmade pouch ★ #sunnyshell flat pouch Width → 20cm Height → 12.5cm Thick interfacing is used(^^) It can easily hold 5-6 bankbooks ★ Also as a pouch for managing bills. A mother and child health handbook also fits!! I try to make them neatly, but as it's handmade by an amateur, there may be some imperfections. Please understand this before purchasing. #bill pouch #bankbook pouch #mother and child health handbook holder #bankbook case
