Review (5/5): Work great
I use these to anchor my ponytail up against my head when I shower, exercise, or want my hair off of my neck. Whether I am actively exercising or laying down on my yoga mat, they hold my hair in place. I bought a set but loved them, so I ordered a 10 pack. I carry one in my yoga bag, my swim bag, my suitcase, and my purse. They seem very durable. I am happy with this purchase.
