C519 Pro Lush Blush by Crown Brush. 

The Pro Lush Blush Brush's compact head allows for a very controlled application of blush. Thanks to the super soft, dense synthetic bristles, this brush can be used with both powder and cream blushes, and provides medium to full coverage for a more dramatic finish. The Pro Lush Blush Brush can also be used in the hollows of the Cheeks and around the periphery of the Face for a more natural and seamlessly blended Contour effect.

Bristle Profile: High Grade synthetic fibers, Incredibly durable, Indefinite lifespan with proper care, Can be used with liquid, powder, and cream cosmetics.
