Okay if you have thick hair YOU NEED THESE!!! I have struggled my entire life to find elastics that I could get around my thick hair more than twice and not break or have them actually hold if I could only get it around twice. This idea is genius and I cant believe how well it holds me hair. My pony is snatched and doesnt move!! Its also not a your normal thick scrunchie material so it passes as a elastic pony tail no problem. I am so so happy with these, especially when I'm working out!
