This toy should only be used for someone with larger nipples. My nipples are fairly small and we had some trouble getting these on. Once they were on, they slipped off within a few minutes. If your nipples are bigger than mine or get more erect than mine do, then these nipple ties would be perfect for you.

Felt like a gel hair band, the beads were quite smooth, though. Didn't have any issues with the metal bells, either. I'm allergic to most metals so that was a very nice surprise. Had a bit of a ridge but it didn't bother me too much. Can stretch quite far but I wouldn't recommend stretching it as hard as you can. Felt kind of weird on the skin but if textures don't bother you then this won't be an issue.

I would like if the bead and the silicone ties were the same color, but they do have a nice contrast as-is. Very easy to put on and take off, although to put them on you'll most likely need a partner to do it while you hold your nipple out. It's very adjustable and you can make it as tight or as loose as you want.
