A brass padlock built for bondage collars. Two keys. Locks on and stays on.

The Brass Collar Padlock from Master Series is a small, solid padlock designed to lock BDSM collars, cuffs, and restraint gear in place. Iron and copper construction with a copper finish. Two keys included. Non-keyed alike.

The shackle fits through the D-ring or buckle loop on most leather and nylon bondage collars and locks the collar in place. The body is compact enough to sit flush against the collar without adding bulk, but heavy enough to have real presence. Works on collars, cuffs, restraint straps, and anything else with a D-ring or loop that needs to stay closed.
