[I want to express my individuality in the business scene as well.] ］ Most business card cases are formal and muted. Some are colorful, I feel that it is difficult to find something that is made of genuine leather and is made of high quality. I don't want it to be too colorful or look cheap because it's used in a business setting. However, even with genuine leather, if it is only black or brown, I find myself compromising something. We have created a business card case for such people that can create a high-quality, yet colorful, and elegant personality. It can also be used as a card case, so it is ideal not only for business scenes but also as an item that colors your daily life as a card case.
