Our Horween Shell Cordovan is a vegetable-tanned leather from Horween in Chicago, USA. Colour 8 refers to Horween's name for a colour that varies between a dark burgundy and aubergine/eggplant colour. This colour varies with the lighting and each shell finish varies in colour. 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 overtime, develops a beautiful patina. Shell Cordovan begins as a high-shine leather and overtime becomes more dull with wear. This shine can be replenished through the application of leather conditioner and brushing vigorously. Tannery: Horween, USA Temper: Medium Surface: Smooth with occasional natural marks, and slightly waxy Patina: High Water Resistance: Low. To ensure longevity, avoid moisture or soaking our straps in water.
