These clamps are great for beginners and experienced players. They are screwed in place, allowing them to be gentle or intense. The feeling is crushing, very similar to being squeezed between two fingers, but when tightened it builds in intensity. They also look a lot more decorative than many clamps, making them an attractive item to wear.
These clamps work well on both women's and men's nipples. They are handmade in the UK. Price is for a pair.
