The only brush you will ever need to apply PÜR 4-in-1 Mineral Makeup or the 4-in-1 Loose Mineral Foundation. The 3-D Method makes application so simple - Dip, Draw and Dust. Dip the brush into the product, draw circles in the lid and dust on in downward strokes for a flawless finish. (For added coverage of those small or hard-to-reach areas, use the PÜR Utility Brush.)
