These clips are mini but mighty measuring at 2 1/2 inches and can hold your hair 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!
