Mister Big Plastic Clamps
Another great pair of nipple clamps from the fantastic Mister B nipple clamps collection. These clamps have a wide mouth so they re excellent for playing with larger or pronounced nipples because they can hold a lot of flesh.
Spring operated, so they squeeze the nipples with constant pressure. Adjustable, so once they re put on, releasing the screws will give a second burst of pleasure once you re used to the first one.
Easy to operate even with slippery or gloved hands.
