This is by far my most used brush from the Mary Kay collection. I've used it for both concealer and cream shadow, it's splendid! It blends in the concealer so well and is precisely enough that you can get into all the tiny troublesome areas. The brush also doesn't get all chunky and gross after 1 or 2 uses like some of the other brushes I've tried. Stays nice and smooth and after cleaning it remains exactly the same!
