Bought all 6 (at the time) colors together and love every one. These clips are super flexible and comfy, I hardly remember they're even in my hair. I've worn them driving, during 10 hour shifts, fallen asleep in them, and never felt any pain, headaches, or discomfort. I was a little worried about the size at first as I have very thick, curly hair but they stay just as well as my dedicated thick hairclip. Bigger sizes would still be welcome though! Glad I gave them a try because these are genuine...
