These clamps fit most nipples, even large ones! They are comfortable and very affordable. They stay on fairly well unless you bounce around a lot. They are pretty with the beads. I find that they are sexy, and they make me sexy and a little naughty! I also think of them as being kinda classy and discreet. The slim design is very nice. They could be hidden under clothing. They aren't made to be extreme BDSM. In fact, they are very beginner-friendly. They are very inexpensive and very easy on the budget, so anyone can try something new and different. Watch that the rubber tips don't come off or get lost. These have been a great addition to my collection.
