A turquoise coin case with a gem-like shine. This coin case uses Roroma leather, which develops a rich texture the more you use it. The vivid turquoise blue color is reminiscent of the beauty of a tropical sea. The surface is covered with a generous amount of white wax called bloom, which gives it a matte texture at first. However, as you use it, the friction melts the wax into the leather, transforming it into a surprisingly beautiful luster and a transparent color. This aging process is the real pleasure of Roroma leather. You can enjoy cultivating your own special shine and texture. When you open the flap, the contents are easily visible, making it extremely user-friendly. Its compact size allows it to fit neatly into small bags. In addition to coins, you can also store cards and keys, making it possible to go out with just this one item. This product was created as a prototype, so there are some scratches and shape imperfections.
