Originally these pliers have a vetinary function but of course we use them for different purposes :-).
We don't castrate rabbits; no, we use them for nipple play. Use these pliers to stretch open one of the 100 small rubber rings and put them on your nipple as you can see demonstrated in the other picture. The further back you place them, the heftier it gets...
One bag with 100 rings is included in this set, and you can buy bags with 100 spare rings separately. Please see the next product below to order them.
