These are the same as our Tweezer Clamps (JT's favorite, and one of our most popular items), the only difference being that they have a plainer style of chain between them, and the price is slightly lower. They have vinyl-coated ends, linked chain, and a sliding ring to adjust the tightness anywhere from just enough to hold them on all the way up to a really severe pinch. They stay on, they are easy to use, they look good, and they can be heavy or light or anywhere in between.
