Abstract: A hair fastener clip for a hollow cylindrical hair roller is disclosed. The roller has a hollow interior defined by an inner cylindrical wall and an exterior wall defining a peripheral surface onto which hair is rolled. The fastener comprises a pair of spaced apart legs and a third leg shorter in length than the pair of legs. The third leg extends downward from the pair of legs for engaging the inner cylindrical wall of the hair roller while lower surfaces of the pair of legs clamp the rolled hair onto the hair roller. The third leg comprises a loop member extending downward from a piece bridging the pair of spaced apart legs, an inclined member extending upward from the loop member, and a terminating end member contiguous to the inclined member and extending downwardly away from the pair of legs. Structural features of the hair fastener clip include a planar handle extending downward from the bridging piece, a bobby pin formed by the pair of legs and bridging piece.
