C525 Pro Round Blender by Crown Brush. 

The Pro Round Blender Brush's round and densely packed compact head makes it the perfect brush for both loose and pressed powders. The small size of the brush allows you to pack powder into those hard to reach areas such as under the eyes and along the bridge of the nose. The ultra soft Capra blend bristles pick up large amounts of powder at a time and easily buff product into the skin, making it ideal for mineral foundations, leaving behind a medium to full coverage application.

Bristle Profile: High grade Capra hair, Easy to clean and maintain with proper care, Incredibly soft yet springy enough to maintain shape and structure throughout countless uses, Natural hair easily picks up large amounts of powder.
