This gorgeous tungsten steel set is perfect for couples who want to show off their Dominant and submissive relationship subtly and with style! The bracelet locks into place when the key that hangs from the center of the dog-tag style necklace locks the heart-shaped lock on the cuff. There are two shining rhinestones set on either side of the lock and the wearer can keep it on long-term for as long as the Dominant partner keeps them bound. It provides an alternative to a collar and can be worn proudly in public without anyone questioning the true meaning of these symbols. The Dominant partner wears the dog tag as a keyholder and the submissive partner wears the cuff-style bracelet instead of a collar. The tungsten steel is strong, scratch-resistant and nickel-free. Measurements: Bracelet inner diameter: 2.35 inches x 1.84 inches, 6.25 inches in circumference. Necklace length: 19 inches. Materials: Tungsten steel, rhinestones Color: Rose Gold
