Thank you for viewing! This is a multi-case that can store your bankbook, medical record book, health insurance card, cards, and various other items. I also use this myself, and it can perfectly store the medical record books and health insurance cards for my two children, bankbooks, and more! ^ ^ As shown in the third image, this product has a sewing error. The back side is sewn properly, so there is no problem with functionality, but please purchase only if you can accept the appearance from the front. 《Size》 Length: 18cm Width: 12.5cm Card pockets: 9 Pockets: 3 ※ Each item is made with care, but please refrain from purchasing if you are looking for the quality of a mass-produced product, as it is handmade. ※ Due to the handmade nature of the product, there may be slight thread shifts or fabric misalignments. Please understand. Thank you.
