This is a handmade item. It can store cards and health insurance cards. There are 16 storage pockets. Velcro button closure. Size (closed): 10.5cm x 15cm I try to sew carefully, but as this is a handmade item by an amateur, please refrain from purchasing if you are looking for perfection. *Please note that there are some sewing distortions, especially in the areas where the Velcro buttons are sewn on, as shown in photos 3 and 4. If you like it, you can buy it immediately.
