Thank you for viewing. This is Kokonoe Leather Works. All items are handmade, and there may be individual differences and imperfections. We hope you appreciate that as well. #KokooneLeatherWorks Why not take a look at our other items? 【Using Special Leather】 We use Himeji Kurozan Leather. This leather is also known as the "black diamond of leather" and is made using the traditional Japanese techniques of "tanning" and "lacquer coating." When you look closely, it has a sparkle like small diamonds scattered throughout, and it is also highly durable. It is said to have been used in the past for armor. This is a card case. It is a very stylish case. It can hold 3 cards, and the two outer cards are easy to take out. One card can be placed in the middle, hidden from view, so you can use it according to the type of card. Also, the stitching on the edges is double-stitched for added strength. Color: Black Material: Himeji Kurozan Leather (Sakamoto Shoten) Size (Individual differences may occur): Width 10.5cm x Height 7cm x Thickness 0.3cm Number of cards that can be stored: Approximately 3 *Items other than the main product shown in the photos are not included. *There may be natural leather characteristics such as wrinkles, scratches, and stains.
