Threaded nipple clamps with weight

Would you prefer a clamp that you can adjust as tight or soft as you wish?

Then these clamps with weights are probably something for you.

The mouth can be opened and closed very far by turning the screw in the middle.

Thanks to this clamp you can even pinch something very finely, e.g. inside or outside the labia, but of course you can also clamp nipples in between.
