I made a small coin case with a zipper. I used Tochigi saddle leather in dark brown for the exterior and cowhide buffalo leather in cognac for the interior. I used beige for the stitching. It's small and very cute. It can comfortably hold about 8 500-yen coins. I attached a swivel clasp, so I think it would be nice to use it with a strap or as a keychain. #elmway001 Material: Cowhide (Tochigi Saddle Leather) Size Height 4.2 x Width 5.5 cm, Depth 2 cm This is handmade.
