Thank you for viewing this piece. This is a pass case made using Tochigi leather. It is all hand-stitched. The case body is made with approximately 2mm thick leather for a sturdy construction, which will securely protect your cards. Enjoy the aging process, as the surface color will change to a beautiful amber over time. Very convenient for carrying around your IC card! It's simple, but I think you'll be able to use it for a long time. It would also make a great gift for someone special! 【Color】 Natural 【Size】 (Card case body, including hardware) Total Length: Approximately 160mm Width: Approximately 75mm 【Please note the following】 ● Because natural leather is used, there may be some scratches or wrinkles, but this does not affect its use. Please enjoy it as a testament to its natural origin. ● The color may differ slightly from the actual product depending on your PC environment. ● Although we take the utmost care, there may be some scratches or scuffs remaining from the manufacturing process. ● This is a handmade item made as a hobby, so there may be some individual differences, but we appreciate your understanding.
