The Butterfly nipple clamps are for advanced users only. I can’t stress that enough. They are hardcore to the max and painful to the bone. If you love nipple torture, and I mean really intense, spine-tingling, ouch-inducing torture, then this is definitely what you might be looking for. Although they aren't my style, they're worth the quality, the functionality, and the price.
Stylish, hardcore, stays on the nips, flawless design.
PAINFUL, too tight, for advanced users only.
