To start off, these are cute nipple clamps that visibly look a little painful to the eye, but just wait... I couldn't let go of the clamp on my nipple because it hurt so bad. If you're a beginner in nipple clamps as I am, then this isn't the clamp to buy. This was my second set of nipple clamps, and I hope to advance to being able to eventually use these, but it hurt pretty bad to apply them to my nipples. Some may enjoy that feeling, but as of right now I don't.

If you have a high pain tolerance level, then this would be a great nipple clamp for you to get. I would think that it's safe to say this set of nipple clamps is for more advanced nipple clamp users than for beginners such as me who have only tried one pair of clamps on. For the price of $14.99, this is a great deal if you can handle the pain it brings. It has a very tight grip when applied to the nipples and a chain that connects the two together.

The black tips of the clamps are made of rubber, and the rest of the clamps and chain are made of metal. The weight is about 1.7 oz and you can definitely feel it. I didn't expect these to hurt half as bad as they did, so I'm going to have to work up to them, so these will end up being in my toy chest until then. They can be a lot of fun for anyone who enjoys this type of play and pain, but for me it'll need to wait until I get more experience with clamps. I will definitely do my best to work up to these, because they are a great clamp, just too much for my liking and threshold of pain tolerance at the moment.

Sizing:
- The sizing of these clamps are only about 1/2 an inch long in length.
- The sizing of this chain that connects the clamps is about 16 inches long.

Cleaning these clamps:
- As most people who are familiar with metal toys know, metal is able to be boiled as well as cleaned with a soap and water.

I was excited to get these in the mail and try out for fun with and without my spouse. I got them out and tried them twice, and couldn't take the pain so I had to put them in my toy chest until I can work myself up to these nipple clamps made by Spartacus.

I give these nipple clamps 3 star rating because they didn't work well for me, because of the intensity of the pressure in them.
