Review (5/5): TOTALLY works!
I'm a low-maintenance girl and really not that into hair accessories, but I saw these for $3 at the store and decided to give them a try. I am BLOWN AWAY by how well these work!
I have long, thick hair. I pulled my hair up like I was going to create a high ponytail, but I did NOT put in an elastic. Instead, I just started coiling it into a bun. Once done coiling it, I spun the first pin through the base of the bun to hold the end of my hair down. Then I spun the other pin across through the body of the bun to hold its shape. I let go and IT DIDN'T BUDGE A BIT. It stayed exactly in place and did not try to uncoil. It stayed neat and in place even when I bumped the bun pretty hard getting into my car.
It took less than a minute from start to finish. SO COOL!
