I've been doing makeup for over 10 years. And since I found this brush (9 years ago), I haven't found another brush that can compare to this brush (and I tried several different brands brow brushes). I like that the brush bristles are firm enough to be able to control how much product you put on and will help you create sharp lines. But yet soft enough where it won't scratch your skin. Hands down the best brow brush ever!!!!!!
