Review (5/5): Must try
I have long, smooth asian hair. When ever I have a bun, I have to constantly redo it because it falls out. These actually do work! My bun stayed secure even through an exercise class. Amazing! I saw the negative reviews of the sharp edges....my pins had the balls at the ends. Maybe one vendor is selling an old/cheaper version. I would definitely recommend if you put your hair in a bun. It takes 5 seconds to twist it in your hair, very quick and easy.
