these do not pinch open wide enough [SEP] these are ok but with my arthritis i find them hard to pinch open far enough to slide them onto my strip of hairalso somehow on their next upgrade they should find a way to make them lighter in weight so they do not pull down from gravity however i am older and my hair is thinner than it used to be thicker hair would probably work just fine especially if you have natural waves and good body to your hair
