Colorful little clips for twist, dreadlocks, braids [SEP] Used at the end of twist. They can be reused if you're not rough with them. Their strength to hold the hair is good, squeeze them in place and they will stay. If you open them all the way and close them often, I'm pretty sure that they will break. They come in a neat little plastic holding case that can be reused. The colors stand out in the hair too.
