Lay flat and relax. The Mulberry Large Flat Round Hair Clip from TELETIES is a 4.25 inch flat back hair clip in deep berry purple, shaped so you can lean against a headrest, lie down, or roll through a yoga class without a clip digging into your head. Mulberry is the shade fall was waiting for, a deep berry purple that looks expensive against every hair color and pairs just as easily with a cream sweater as it does with black denim.
