This is a convenient case featuring a gentle yellow pastel Moomin pattern. It's perfect for storing things like insurance cards and medical appointment cards, and is easy to take with you when you go out. It fits a size M (approximately 18cm x 13cm) maternal and child health handbook. It has side pockets for easy access to documents. The core material prevents it from losing its shape, so you can use it with confidence. You can also use it as a multi-case after you no longer need it for your maternal and child health handbook. I used it for about two years, starting in 2022, but I'm selling it because my child has grown and I don't use the maternal and child health handbook as often. It has been used a bit (see photos 3 and 4), but it's in good condition with no noticeable stains or scratches. Thank you for your consideration.
