This is a versatile multi-case with various uses. It can be used as a passbook case, a mother and child health handbook case, or even a goshuincho (temple stamp book) case, a mask case, or a tablet case. The lid is made deep to allow for flexibility in what you put inside, so there are no hooks or buttons. This allows for smooth insertion and removal. After being made into a bag shape, the edges are sewn for durability!
