The crisp color is fashionable. Introducing the "silicon coin case" found at the 100-yen shop CAN DO.
Folding coin case made of soft silicone rubber. The size is about 58 x 53 x 17 mm thick.
Available in four colors: pink, yellow, navy, and black. The colors that are crisp but slightly off the royal road are fashionable, reminiscent of product designs around Germany and Italy. All completely plain.
Not only coins, but also accessories, medicines, and soft materials make it suitable for inserting SD cards. It's fashionable to distinguish by color and use more than one.
I don't like the swelling of my wallet, so I'm considering introducing a coin case, but if you don't know if you'll continue to use it, you should buy a good leather one. If it's a different material, unlike synthetic leather, it's less likely to be cheap.
