  • Publication number: 20060225763
    Abstract: An improved hair clip and method of making a hair clip is provided. More particularly, the engaging members of a hair clip are provided with a cushioned surface that does not need to be attached to the external surface of the engaging member. Rather, the engaging members of the hair clip may be formed with holes and the outer cushion surface may be formed by material that protrudes through the holes in the engaging member. In one embodiment, the cushion material may be injection molded into the hair clip in a manner that results in the cushion material being forced through the holes in the engaging member in order to form a surface that may contact the hair.
