Thank you for viewing! This is Kokonoe Leather Works. We use good quality leather and everything is handmade, so there are individual differences, and no two items are exactly the same. We hope you will appreciate that as well. #KokooneLeatherWorks Would you like to take a look at our other items? 【Using Special Leather】 We use leather called Himeji Kurozankawa. This leather is also known as the "black diamond of leather" and is made using a manufacturing method that combines 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 that it was once used for armor. This is a business card holder. It can hold about 20 cards. The width is generous for standard business cards, so you should be able to fit slightly wider cards as well. You can put one card in the lid. Also, you can put one card on the outside of the main body, so you can prepare it for easy access. The lid will open, but the leather will become familiar with use and the shape will be set, so it will eventually stop opening.
