These clips are mini but mighty measuring at 2 1/2 inches and can hold your back in a half up half down without creasing it. We recommend stacking 2 in one if you have medium to thick hair. They are unique, sturdy, and so stylish. ALSO added bonus that they are flat, so you can pull your hair back in a 'claw style' and still be able to lay your head on the headrest when you drive, or lay down flat without it hurting your head! They come in six different colors: nude, deep tan, terracotta rust, deep lavender, green and blue!
