Review title is No teeth [SEP] If you have hair that doesn't hold barrettes well, then these are not for you. There are no teeth on their underside to keep them from sliding. I tried a few times to wear these and they ended up sliding down my hair through out the day. I don't have time to keep adjusting my hair. It was so annoying. I am past he time for a refund.  All the shapes are fun. You could wear more than one but that's just more that end up falling. I don't recommend this item. Not worth the money.
