Coin Card
Coin Card

The Coin Card looks like a normal VISA card but it is a useful tool for managing spare coins. It has an interlayer so you can put coins into the Card and take them out easily when in need. In addition, you can see the number and value of the coins inside your card so that it will be convenient for you to manage them.
