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 these as part of the charm. #KokooneLeatherWorks Would you like to take a look at our other items? 【Using Special Leather】 We use Himeji Kurozankawa 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 scattered small diamonds and is highly durable. It is said to have been used in armor in the past. This is a business card holder. It can hold about 20 cards. The width is generous for standard business cards, so it can accommodate 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 may open initially, but the leather will become familiar with use and take shape, so it will eventually stay closed.
