Review (5/5): Can hold long-ish hair in one bunch
My wife loves these hair clips. We didn't read the length when we ordered them, and they're larger than the standard hair clip you get at the drugstore.
She says these are big enough to hold all her hair in a single bunch without having to fold it back on itself three times like with a normal clip, so it's easier, comfier, and dries much faster if she puts it up out of the shower. The teeth are long enough to grip all her hair securely so it doesn't start falling out if she is moving around doing stuff. She finds this clip a comfy and fast way to get her hair off the back of her neck. Do recommend!
For reference, her hair goes a bit past the bottom of her shoulder blades, but not quite as far down as the small of her back.
