Add a new level of meanness and pain to your nipple play with these Tyrant spiked clover clamps! The meanest of our collection, these Japanese Clover clamps only intensify in pressure as you pull them or put weights on them! Instead of a soft, flat, or padded clamp, these have round-tipped, spiked, metal clamps that really bite down on the nipples and areola! Enjoy adding some spice to your pain-and-pleasure play! The metal can be heated or cooled to add as part of a temperature-play scene. To clean, us warm water and mild soap, then rinse with water and pat dry. All metal is nickel-free for sensitive skin.
