I am assuming makeup brush, and I have two. Both are incredibly reasonably priced.
It's a very soft, natural hair, PINK kabuki brush. I have another kabuki brush that I almost never use. This one is the bomb. I've had it for a few years and use it almost daily. I was it regularly and it's been a trooper.
Price: $1 (for real)
I seriously own three of these brushes. Not because they fall apart or anything, but because you never know when you're going to use multiple bright colors in one day or not feel like washing your brushes. I love this brush.
