DEFY's workshop is less than 8 miles from the century old, iconic Horween Leather Tannery in Chicago. We don't take this for granted and go weekly to find the best possible leather for our lines. Austin Calf leather is quite special. It's color and patina only improve with time. This key chain has an antiqued brass clip and sports antiqued brass rivets. It's hand-painted and polished in Chicago from the finest leather in the country. Your keys deserve it!
