Only on female nipples.
Very light. They are the only metal clamps that do not pull the nipples down.
They retain the submissiveness and challenge while being comfortable and non-slip.
Easily adjustable by pressing - for smaller nipples, the wire must be bent to the centre by pressing (i.e. to reduce the hole in the centre). Adjustment - bend the wire away from the nipple.
