These hair ties are some of the best I have used. I have thick hair and most hair ties pull my hair out. With these ones, my hair doesn't get pulled, they hold nice and tight, and they are made to last. They don't have seams or clasps on them where something might get caught on your hair and pull. They are the perfect thickness for my liking. They are very comfortable and do not make my head hurt. Even though they are very stretchy, they also do not slide out and make your hair fall as the day goes on. I definitely give these hair ties a 5 star thumbs up.
