These nipple clamps are perfect for use if you are a beginner, but advanced nipple play users will love the irresistible little bells. These particular clamps are in a "v" shape, with a small O-ring on the bottom. In order to adjust the clamps, all you need to do is to slide the O-ring upwards. You can vary the intensity quite a bit this way and make them anywhere from "firm" to "super mega omg tight!". More advanced users can make the "bite" a bit firmer by removing the rubber nibs at the end of the clamp.

I also tried putting these on my labia, and they were just as fun there too. My husband and me both enjoyed the "tinkling" noise that these made quite a bit, and they felt great on as well.

These clamps are made from metal, but they also have rubber nibs and two pink plastic beads attached to each one. There was no smell coming off the toy at all, which is a plus. The rubber nibs are quite smooth, which is a bonus that beginner users will definitely appreciate. The bells themselves are very smooth as well, and they are very pretty to look at.

These clamps are the perfect shape. The rubber nubs are perfect for making sure you don't scrape your nipples up, and help to make the toy's "bite" easier for a beginner to take. The clamp opens up to approximately .75", and clamps down to less than a quarter of an inch. This is really great because it covers a wide variety of nipple sizes.

They are really easy to get on and off, I recommend holding onto the clamps near the top, and carefully sliding the O ring down, because these clamps have quite a bit of tension, and just pulling them off will hurt quite a bit, especially if you have removed the rubber nibs for a more "pinchie" feeling.

I was very surprised by how well these stayed on, once the O ring was put into place. I put the O ring up three quarters of the way, and found these clamps to be in no way painful. I was able to wear them for about 15 minutes without even feeling like they were on at all.

The toy came in a clear plastic container, which was really easy to get open. Simply slide the cardboard backing off of the plastic, and your clamps are ready to use. The entire package was recyclable, which is always nice.

These clamps are very fun for both beginners and advanced users of nipple toys. I found that the bells made a lovely little "tinkle" noise, instead of a ringing. I was also surprised by just how light these are. I had thought that the bells would pull the nipples a bit, but once you get them on, you really can hardly feel them! They are so light!

One thing to think about with these is that, because they are so light, if you aren't checking on them often, you might not realize you're wearing them for too long. Make sure that you check the skin often, and if it starts to turn purple, it is time to remove your clamps. I was able to wear these for a much longer time than normal clamps, because of the low weight.
