Size: Approximately 20cm (height) x 15cm (width) Inner pocket dimensions: 19cm (height) This is a highly functional mother and child health handbook case, size S. It has 15 pockets, including double zippers. It fits size S mother and child health handbooks. Sizes M and L will not fit. I purchased it for around 6000 yen, but I no longer have a use for it, so I'm offering it for sale. I used it for about two months. It was mostly kept at home.
