TSUTSUMU Card Case was brought to life based on the Japanese custom of wrapping valued items carefully, such as “furoshiki (a large piece of cloth used to wrap objects)”, “noshibukuro (a special envelope used for gifts of money)” and “fukusa (a square piece of cloth used to wrap the noshibukuro)”. It is made by folding a piece of leather – beautifully, like origami – without using any fastener. TSUTSUMU is designed to gently wrap your valuable business cards. The pleasant texture of the leather becomes better and richer as it ages. It looks stylish in business situations while also expressing users' elegance.
