Very nice clamps, open weave chain will accept weights with an ^S^ hook. Clamps have a removable insert and serrated teeth on the gripping surface. Rather strong grip, may not be suited to beginners or those with sensative nipples.

These are great! I actually use them while I'm fucking my self with the Holmes suction cock. I love hard pressure on my nipples, but these are not quite tight enough. Great for beginners...
