The material is made of high-quality chrome. It has no odd smell. What's great about nipple clamps is that you can easily apply temperature play to them. You want your partner to be nipple tortured by freezing cold clamps? Or clamps that are hot? The material is perfect for that. The rubber tips are nice and smooth, which makes using these clamps slightly more comfortable.
Typical of all nipple clamps, the design and shape is with two clamps attached by a 12-inch chain and looks so aesthetically pleasing when worn. The chain can also allow for one to add weights if necessary. Using these clamps is easy; loosen the screw to where the clamps are wide open, place your nipples in between the clamps, then tighten the clamps by tightening the screws until each fits firmly and comfortably, and the clamps won't instantly fall off once worn. Naturally, the tighter it's worn, the more painful it is, and the more pressure one will feel. Also, keep in mind that if you have really tiny or petite nipples (like me), you will have to adjust it frequently to ensure that it is a firm and tight fit. If you have larger nipples, you may not have a problem. Communicating with your partner is necessary to make sure that there isn't too much pain applied when wearing these clamps. Can these clamps be painful? Yes...but only if you want them to be.
