This multi-pouch has a zipper that opens to reveal three pockets with plenty of depth for secure storage. (The middle pocket is a bit smaller.) It can hold unfolded bills, making it convenient for handling money at the bank. I think you can do everything with just this one pouch. I manage six bankbooks, and this one is enough. You can also use it to hold your medical record book for doctor's visits. It can store your medical record book, insurance card, medication instructions, and receipts. The inner fabric is unbleached cotton, and the zipper is gold. Size: 13 cm (height) x 21 cm (width)
