When you're in the mood for something a little (a lot, actually) intense, nipple-wise, the Master Series' Monarch Noir Clamps have you covered... and pinched!

Unlike most clamps, the metal Monarchs are not adjustable. At all. The textured tips bite tight immediately and get even tighter when tugged. You can even add weights (not included) to the connector chain for even more sensation. 

Total length: about 19.5"/49.5cm, Each Clamp: 3.5"/9cm long, 1.5"/3.8cm wide, Connector chain: 12"/30.5cm
