Each and every bracelet is made using the highest quality grade leather that is cut, stamped and dyed before being designed. 28 or higher gauge steel pieces are used for the metal works. Each piece is handcrafted and no two pieces are alike. When you own a Brunner's Metalwear bracelet you can expect to be wearing a one of a kind piece. When you see the Brunner wax seal, it means you own a genuine piece of perfection.
