Review (4/5): If you have thick hair, you're going to need a second pack
I really like these curlers, but it wasn't nearly enough for my hair, even though my hair isn't very thick. I thought I could just put a little more hair in each of them but I had a very hard time pulling the hair through, and even then a quarter of my head still wasn't covered. But otherwise super easy to use and much more comfortable than other overnight hair curlers.
