Review (4/5): A good buy.
The good thing about the bonus is that they are affordable. The headband is quite comfortable and the material doesn't stick to your hair which is good. The bad thing about it is that it's not as big as I thought it would be, not that I needed to be, but just based off the pictures it seems like it should be a little bit bigger. But overall 11 bucks for four you can't be so I think it's worth to buy!
