ISAMU KATAYAMA BACKLASH leather case. It uses Italian oil leather, and the lining is also the same Italian oil leather. It's been used quite a bit, so it has a strong luster, and it has a shine like cordovan leather. Although there is a feeling of use, it is a very high-quality leather, so you can still use it for a long time. It's small as a clutch bag. Recommended as a bag-in-bag for passbooks, passports, writing instruments, and other small items. This product is not often available. I think it's good for organizing your bag or for a short outing.
