Each of these shoulder bags are a one of a kind custom made item. No two bags are the same. Each bag is stamped with it's individual number. The straps are adjustable. There's an inside pocket and heavy weight leather is used throughout. No machine stitching is used for assembly. We only use rawhide whip stitching with grommet enforced holes or rivets for construction. These unisex shoulder bags are a revamped 100 year old design and virtually indestructible. With proper care this bag should last well over 100 years.
