Review (5/5): Excellent for securing hair in bun.
Living in FL with long hair (down below my waist) I keep it up in a bun most months. I used the goody classic claw clips until I was introduced to the Style Spin pins. They often left me with headaches & they didn't last long breaking easily.
A friend of mine introduced the style spins about two years ago & I am thrilled with them. They are easy to use (take a bit longer than the clips but only seconds), they do not pull on my hair so have not given me a headache one time.
I have used both the long pins (like the ones I'm reviewing) and the shorter pins. Both work equally well. Smaller ones are better for thinner and/or shorter hair, longer pins are better for thicker and/or longer hair. Regardless you could probably use even the shorter ones you would just need to use more of them. I have very long but thin hair & use either two short ones or one long one.
The downside is I lose them easily and they are not easy to find in stores.
To Use:
Personally I pull all my hair together like I'm going to put it in a high pony tail. I then spin it until it is in a fairly tight twist, then spin it in a bun. Once in a bun I put spin one or two of the style spins through the bun until it is secure.
