Make your fantasy a reality. Cuffs wont come apart unless you want them to. Unlike the disappointing keychain-grade hardware featured on many restraint cuffs thats so easily pulled apart the industrial-strength hooks sewn firmly to these cuffs attach them quickly and securely to furniture or to each other. Each cuff measures up to 10 inches around when the nylon webbing straps are fully fastened. The crab claw-style hooks rotate fully to prevent tangles or uncomfortably twisted arms and guarantee that these cuffs hold fast-till you pull apart Velcro. Hooks and hardware are nickel-free to prevent allergies.
