Perkify your love buttons and enjoy increased sensitivity and arousal from each lick, nibble and twist that follows. Made for intense stimulation and not for beginners, these nickel-free nipple rings stay in place, leaving your hands free for other fun. To use, gently pull the rings so the metal balls part and place your nipple in the gap. Be prepared for intense stimulation from the get-go thanks to the silicone-free design that gives direct metal-on-skin contact. If you like it really intense, pull, tug and twist the clamps to amp the sensation even further.
