The intended use of these is pretty clear. They're meant to be applied to your nipples as nipple clamps. That said, you can easily apply them to other areas of your body. For instance, assuming that they fit your clitoris, you could easily use one of these as a clit clamp. Personally, I have only used them on my nipples.

These clamps are a great choice for both beginners and advanced users. This is due primarily to the fact that these clamps are highly adjustable. For those of you who just want the look without the pain, it is easy to adjust these so that you can barely feel them. On the other hand, for those of you that want to feel a strong pinch? These can be adjusted to serve that purpose, too.

For those looking for really intense nipple clamps? You're probably going to want to look elsewhere. These clamps do have a powerful pinch at their tightest setting, but they're so light that they're just not going to be for those seeking intense, or extreme, experiences.

As for what gender these clamps would best suit? I cold see them working wonderfully on both male and female users, and on a wide variety of nipple sizes due to the adjustable nature of the clamps.

The main body of the clamps is made out of metal. The packaging does not state what kind of metal is used. The sleeves that cover the tips of the clamps are made out of a material that feels like rubber. The packaging does not say what kind of material the beads are made out of, but they feel as though they are made out of plastic.

The metal on these clamps is non-porous, and both latex and phthalates free. I am not sure about the rubber-like sleeves, as the packaging does not specifically state what they're made out.

Both the metal and rubber-like sleeves feel very smooth to the touch, and neither have any odor at all.

These tweezer clamps are about 4" long in total - 3" without the beads. They are extremely lightweight -- so lightweight that you won't really feel them unless you have them adjusted tightly.

The bulk of the clamps are the tweezer design. The very ends of the tweezers are covered with a rubber-like sleeve. The sleeve can be removed easily if you desire a more intense bite. With the sleeves removed, one ca see that the ends of the tweezers are angled inward, and are sort of squared. The ends do not feel sharp to the touch, however I worry that they may break the skin if the clamps are on tightly enough. For this reason, I won't use the clamps without the rubber sleeves.

The little beads hanging off the end of the clamps are mainly for show, but they do also provide a little bit of weight to the clamps. Still, these clamps are incredibly light.

These clamps are adjusted by a little metal ring. You simply slide the ring up to tighten the clamps. The higher the ring is? The tighter the clamps get. To loosen the clamps, you simply slide the ring back downward. It's really that simple.

Be careful when storing these as the rubber tips can (and do sometimes) come off. I personally store these on the top shelf of the Original ToiBock, but they could easily be stored in other places. If you do decide to store them in another place, I would recommend putting them in a pouch or plastic bag in order to ensure that the tips don't get lost.

As these are simply worn on the nipples, I haven't found that I've had to wash them too often. When I do wash them, I simply wipe them down with a baby wipe.

One thing that you're going to want to remember is that clamps hurt a bit more when you first remove them. To sort of lessen this pain, I would recommend removing them slowly, and even massaging your nipple once they're off.
