Thank you for viewing. I used the Shosa card case as a business card holder a few times, but I am selling it because I purchased a new business card holder. I have only used it a few times, so it is in a clean condition and the leather is still stiff. The black spots seen in the photos were part of the original design. Leather: Cowhide Leather Hardness: ★★★★★ Engraving Color: Silver Size: W12 x H6.5 x D1.6 cm Storage: 2 card pockets * Approximately 30 cards can be stored, depending on the thickness of the business cards. The leather material is resistant to deformation and suitable for formal occasions. (It will change to a shiny appearance) Made with a cowhide base and containing a lot of oil, you can feel the weight and sturdy texture among the leathers used in the Shosa series. You can enjoy the aging process so much that you forget the original atmosphere, and it doesn't become too soft even after using it, which is a reassuring point to nurture. We pay close attention to inspection, but please forgive any minor scratches or stains.
