Purchased from the official Familiar online store in November 2025. I opened it from the bag and tried putting in documents and cards once, but the size didn't fit, so I've been storing it at home. The larger one can store stationery, stamps, and documents up to B5 size. The smaller one is the perfect size for carrying around small items like medical cards, mother and child health handbooks, and postcard-sized items like planners. Since I've put items in it once, please refrain from purchasing if you are concerned about this. Large size: Approximately 21cm tall x 28cm wide (B5 size) Small size: Approximately 13cm tall x 19cm wide (A6 size)
