this, along with the other sigmax brushes from the line, is one of my favorite foundation brushes! liquid, cream, mousse, you name it! it buffs everything in like a dream. it's my absolute favorite for my maybelline dream matte mouse & l'oreal smoothe souffle, and i can't wait to try it with the new revlon colorstay whipped.
