This is a convenient 3-zip type. It can be used for a mini pouch inside your bag or as a foreign currency wallet for overseas travel. I used it a few times and then stored it at home. I used it as a foreign currency wallet for overseas travel, so it wasn't used very often, but please only purchase if you understand that it is a used item. No comment purchase is OK.
