Want a tiny toy with both buzz and bite? Each of these alligator-clamp style nipple clamps is weighted with a small bullet vibrator for a little extra tug and plenty of tingle. Alligator clamps function like clothespins – and tiny pressure screws allow the user to increase or decrease the tension of the clamp. The bullet vibrators boast three intensity settings and are powered by easily-replaceable LR44 batteries. (Available anywhere hearing aid or watch batteries are sold.) These clamps are made of nickel-plated steel and may irritate sensitive skin.
