The Brush is suppose to remove lent, dog or cat hair ect..At first I was not sure about it. But the more I use it..I'm now kinda loving it. I like how it has a cover so you can take in anything. It fits in a gym bag ,purse and you can even put in the glove compartment of your car..It has come in handy. And it will save me money in the long run cause i will not need to but the sticky kind!
