Men's ostrich skin (leg) and black cowhide leather cuff. The width of this bracelet is a half inch wide. The bracelet will comfortably fit an average sized mans wrist, the length from end to end is approximately 8 inches. The outside is real ostrich skin and the inside that touches your wrist is lined in black calf leather sourced from a New York domestic supplier. The sterling silver box clasp was formed from sterling sheet. There are 2 hidden magnets within the box clasp that allows the wearer to easily take the bracelet on and off without added assitance. I recommend you keep this stored in pouch and do not get wet.
