I used it for about two days. I bought it at a store for about 4000 yen. It's easy to use and convenient, and it holds a lot of cards! Height: 9 cm, Width: 10.5 cm, Thickness: 3 cm There's a small scratch? on the bottom right of the back from when I bought it. (See the circled area in the fourth photo) It has a coin case that closes with a button and 6 card slots!
