I love these because aside from being really cute, they don't leave pony tail lines in my hair nor do they hurt my head. These are my go to when I want to throw my hair up in a pony tail, bun, or even a braid. They do get stretched out with use but you can get quite a bit of use out of one before needing to move on to the next one. I had one last me 3 years before I had to trash it. This is a great purchase! Especially for those who want their hair to be secure without being too tight.
