The bristles are dense and thick, and very straight. Makes stippling foundation easy. I bought this brush a few years ago, and loved it from the start. Its just a great quality brush.

However, at $42 a piece, the price is extremely steep. If I wrote this review a few months ago, I would have given this brush two thumbs up and advised you to run out and buy it. I used to swear by this brush until I discovered the Sephora Pro Foundation Airbrush Brush #56. That costs $32 and I find is a much better brush. So anyone looking for a foundation brush, before you shell out your cash for this one, go over to Sephora and check out their #56. It's an even better brush, gives an even better finish, and is extremely easy to use. To top it off, its $10 cheaper. Can't go wrong with that...
