Our Briefcase is made out of 8/10 oz. leather that is sourced and tanned in the USA. We use stainless, brass, or nickel plated brass hardware and polyester thread for superior durability. We hand punch each hole and hand set each rivet. Briefcases include thin rigid supports on front and back panels and are lined in suede to keep electronics safe. Briefcases are available in black or brown leather.
