Tweezer Clamps are the cheapest and usually the most popular with novices who havenít used nipple clamps before. They are shaped like tweezers, as their name suggests, and are long and thin with an adjustable tension ring that you slide closer to the end to tighten around the nipples. This type may be a bit confusing to use at first as some people try to place the nipples between the pincher ends, rather than in the wider space where they are supposed to go. Donít do this. It can be very painful, as Iíve learned from experience. These types of clamps are also a bit finicky to put on and adjust if you are a bit clumsy or have larger fingers. I actually do not recommend these for beginners even though they are cheaper because they are the most difficult to use, and if you are not careful, you can slide the rings to tight and pinch the nipples in them, which really hurts.
