Review (5/5): Why didn't I invent these! GENIUS!!
These things are awesome! Wish I had found them before. My daughter has VERY thick, pencil straight, and LONG hair. If we used babby pins, we use about 15 pins to keep a bun in (and that's with a LOT of hair spray). Nothing holds her hair up, but we only have to use 2 of these spin pins to hold her hair up in a bun! And it stays very tight all day long, especially if you can get the two to lock into each other. Excellent product!
