I'm a sucker for interesting hair hardware and thought these might make an easy, messy but stable, bun. Unfortunately, the length of the pins is a little bit longer then the width of my bun (my hair is medium-thick and falls a few inches below my shoulders.)
These get 2 stars, because they didn't work for me but I gave them to my friend who liked them. I tried them in my hair and my daughter's hair. They slipped right out, but then we both have super straight, slick hair. My friend has a bit of wave to her hair and they worked fine for her.
I have fine hair, and I have a ton of it. I have tried this. I've had someone else try this in my hair. They just do not hold it.
