Natural Shell Cordovan Bund Strap from the tannery Shinki Hikaku in Kobe, Japan is one of the finest shell cordovan tanneries. Our Shell Cordovan is a vegetable-tanned leather from Shinki Hikaku in Japan. Shell Cordovan is famous for its gorgeous shine and unique crease-resisting property due to the density of the leather. It requires very little maintenance and over time, develops a beautiful patina. Shell Cordovan begins as a high-shine leather and over time becomes more dull with wear. This shine can be replenished through the application of leather conditioner and brushing vigorously. Bund straps are a way to give your watch a unique bold look. Originally crafted for pilots, the bund strap features an extra piece of leather within that protects the wearer's wrist from extreme temperatures that could make the metal of the watch too hot or cold against the skin Tannery: Shinki Hikaku/Leder Ogawa, Japan Temper: Medium Surface: Incredibly smooth with a natural sheen Patina: High Water Resistance: Low. To ensure longevity, avoid moisture or soaking our straps in water. We will email you after your purchase to confirm the details of the bund pad.
