Finally a hair clip that grips! Lucky Grip Clips are made of a strong plastic resin that holds its shape and will not bow when holding thick hair. To give it a strong grip, we use a large gage spring wire. This wire loops the upper and bottom jaw to give an even and consistent pressure for a sure grip. Finally, the upper jaws have teeth that grab and hold the hair in place. These Grip Clips come in a black glossy enamel finish.
