I used this to hold my employee ID, but I no longer need it, so I'm giving it away. I kept my employee ID in it in my chest pocket for about 5 months. The following is a description of the product. A pass case that can hold cards and commuter passes together. It can hold a total of 6 cards, both inside and outside. There is a windowed pocket on the inside, which is also recommended for storing frequently used driver's licenses and employee IDs. There is a pocket with a zipper on the back, so you can also store coins. You can attach a separately sold strap (sold separately) to the top金具, so you can hang it around your neck or attach it to your bag. It has a snap button, so the contents won't fall out in your bag. It is a versatile item that can also be used as a pass case because it reacts to touch when you put IC cards and commuter passes in it.
