If you are into some seriously hardcore nipple torture then these bad boys are a must have for your toy chest. Based on a very simple engineering concept these bad boys will put the hurt on your tender nipples. The key to the tightness is in the end, no not the business end, the other end where the chain is attached. The harder you tug on that chain the tighter they get.

While this in itself isn't all that important, it's a key element when putting weights on the end of the chain. The more weight you put on, the stronger they grip and this isn't to say they can't slip, because they do. Trust me, when they slip, that's a whole other level of pain. It's for this reason and many other that these are considered advanced, hence why beginners need not apply.

The clamps themselves are beautifully designed, these in particular are made out of a food grade metal, of which type I apologise I am not sure. If I had to take a guess I would say food grade stainless steel due to that "metallic" smell that rubs off on your hands. I don't notice this smell in many of the aluminium toys and objects I have. The visual appeal is nice, done in a black with a black anodised chain. I did notice a slight bit of chipping to the clamps themselves but only in one spot and after having been tossed around our toy bag for quite awhile. The pads at the business end are held on securely with 4 bent metal prongs and are done in a complimenting white color. The pads themselves have 5 raised nubs on the surface, I did not notice much difference of the texture, I'm going to assume the nubs are there for more gripping potential.

There are many different versions of these guys out there and it's up to personal preference what color you choose to purchase. We liked the black and have a couple of pairs in black and several in silver.

We've used this style of clamp for several years now and even still to this day there are times where it's almost unbearable to have them on. Take note though that the longer you keep them on, the worse it is to take them off. And while these clamps are almost always billed as nipple clamps, they are GREAT on other body parts including the testicles, labia, the under side of your arm and other extremely sensitive spots. Basically anywhere you want to pinch and inflict lots of pain these guys are your go to implement.

More advanced play with these includes attaching weights to the chains, dropping said weights,and leaving them on for significantly longer and longer periods of time (be careful with this to not cause permanent damage).

These still remain my all-time favorite clamps to use. I stick by my review: do not attempt these unless you're ready for a bite! Left on for a few minutes, you can get sore. Left on for 30 minutes and you feel the slightest movements against your nipples. Left on for 45 minutes or longer and you'll experience sweet agony (if you're into that!) when they're removed. There are very few things that will drop me to my knees other than the removal of these guys if left on for a long time.

Disclaimer: Use caution when using any sort of clamp like this. Blood supply is cut off to the area clamped. Always err on the side of caution, really limiting the play of one area to 30 minutes is recommended.
