Review title is Light weight, bendable plastic. Not the cheap flimsy type that breaks. BARGIN at this price! [SEP] Light weight, bendable plastic. Not the cheap flimsy type that breaks. I purchased the to hold my hair up off of my neck to stay cool during the summer months. Perfect for my hair. If you have really thick hair, I do not know how they will work for you because the teeth are pretty short but overall, I am very happy with these clamps. If I had purchased these in a local store, they would have been about 12 - 15 dollars. BARGIN at this price!
