These are not built to last. They are made from cheap materials with a poor finish. The magnet strength is pretty strong and should please most. They should fit any nipple size with no problems. If you can get over the cheap materials, then these would be a good purchase and addition to your toy box.

Disappointing. I wish I had better things to say about the product. It just really did not do it for me. I can't say it enough. Go back to the drawing board and try again.

When the only thing that I can find in a product is that there were rhinestones, I think there is a massive problem. These are not made of steel, don't pinch at all, and can't even stay on pierced nipples when they are magnetic. There is nothing about these that I can do to make them functional short of tying the ends closed.

I think there are a few slight design flaws, but other than that they're good for what they are: reasonably priced, decorative clamps.

These clamps are expensive for what they are. They don't stay on because the magnets are too week, and the magnets themselves have fallen out of my clamps on more than one occasion. Not to mention: they aren't even useful as decoration. What a shame.

These were not worth the price and ended up in the defunct toy drawer. They slid off my nipples every few seconds which, of course, is not the point of clamps. I'll be going back to my butterflies - they might not be as playful, but at least they work.

I simply wish that we had bought these sooner. They are a very high quality. They will have a long life. This is a toy that has found its way into our play time and opened the door to more ideas. Again - I cannot stress this enough - they are HOT as hell.

I had high hopes for these clamps, because they looked like they'd fit in well with a medical play scene, but I was let down by the poor craftsmanship and lack of forethought in the design. These may work for you if you have a very distinct nipple shape, but everyone else is going to be out of luck.
