This is a handmade item. I am also selling on other sites, so please comment before purchasing to confirm availability. Passbooks and medical record books fit. There is a pocket that can hold three cash cards and health insurance cards. It can also be used as a mask case. Passbook case Size Length: Approximately 12cm Width: Approximately 20cm (sewn on the outside with 5mm, so the inside is 19cm) There may be some errors due to amateur measurements. Please purchase if you understand. I work during the day, so my replies will be late. Thank you for your understanding.
