The weighted nipple clamps made by Cal Exotics are surprisingly very well made. I was very happy to know that these nipple clamps worked in a way that were just perfect. The weight feels extremely nice when it swings back and forth. The sensations in my nipples (or wherever I put these clamps) feel very pressurized and very sturdy. I really enjoy some pain and pleasure play. These are made for moderate to advanced pain lovers. I know you'll love them.
The most helpful critical review
If you want a pair of clamps with weights and look nice, these may work. If you have an above average bra size and want ones that will actually stay on, look elsewhere. These are nice in idea, but just do not stay on for me.
