The grey Diamond Pin magnetic nipple clamps by Ouch ensure that each delicate nip is tightly squeezed between the two sides of the powerful nipple clamps...and you decide how much painful erotic pressure they can handle!

The nip clamps are also great for sensual temperature play. Simply put them in a bowl of hot water to fire things up or stick them in the freezer to cool things down.

The clamps are made from sleek aluminium, are totally body-safe, hypoallergenic and very easy-to-clean.
