Sorry to keep you waiting.
 Storage key holders now available.

 Inside the leather case measuring 15x8.5x2cm (width x height x bottom width) is a 30mm diameter pendant.
 It has two leather straps with rings attached.
 The key is attached to the case and stored inside. The ring is gold.
 It is color-coded in silver, so you can use it for work, home, car, etc.
 It can be used to separate things like:

 The outer material is grained cowhide leather, which will deepen in color with use.
 It will become more lustrous and softer and more supple.
 The interior lining is also made of leather.

 There are six colors available: red, camel, green, brown, navy blue, and black.

 The price is ¥16,000 (including consumption tax).

 I keep my store's security IC card in this key case.
 You don't have to search for your card when opening and closing the door.
 I put it in my bag and go shopping at the convenience store.
 Replacement and repairs are also possible.

 I've been using it for years now. It's a very handy keychain.
 Please consider purchasing it.
