Focus pain and pleasure when you try out this simple but erotically effective nipple clamp chain combo. Made of two strong rubber-tipped endurance style clamps, the central chain is lightweight enough for extended wear, but with just the right amount of heft for arousal. Endurance clamps have a tight hold and are best suited to experienced nipple clamp enthusiasts. This pair offers a wider tip, perfectly suited to larger nipples. A great way to enhance BDSM and kink play, the clamps remain taut with a central spring design, and are not adjustable. Color: Black Tips, Silver Chain. Type: Nipple Clamps. Material: Metal.
