This is a thin, black coin case, the size of a credit card, with a thickness of 2.5mm. It can hold the following coins: 1 x 1-yen coin, 1 x 5-yen coin, 1 x 10-yen coin, 1 x 50-yen coin, 1 x 100-yen coin, and 1 x 500-yen coin, for a total of 666 yen. It's about the thickness of three credit cards, so it won't weigh down your wallet. You can also use it as a small wallet by putting it in a pass case. To use the coins, insert them into the holes and push them out from the hole on the back. Multiple purchases or combined purchases with other products are possible.
