Big Gimmick [SEP] It is a waste of money. I received it yesterday in the mail. Now I have long thin hair. I have tried it and kept snapping shut as I was rolling my hair in a bun. Reminds me of an item similar to the snap bracelet. Then when I tried to unroll my hair it started pulling my hair. Save your money, it not worth the hassles. If it wasn't for the pictures on the package I would never know how to use it. Description and instructions are in the Chinese language. I would not recommend this, not a good item use for hair. I ended up throwing mine away. Rips easily. I would not recommend to any my friends. They are cheap and horribly made.
