What it is: A flat brush for the precise application of all types of powder and blush. What it does: This brush's natural goat hair bristles form a high-density flat brush head that applies powders smoothly across the entire face, including facial contours and hollows. The cone-shaped stem allows you to grip near the brush for heavier coverage or toward the tip for more subtle effects. Made of aluminum, the stem's ultra-light weight balances the brush perfectly in the hand. What else you need to know: Intelligent Tools. Innovative Technology. Sephora's I.T. brushes are the result of a collaboration between French designer Philippe Di Méo and the Sephora Pro Beauty Team.
