H614Pi Slide Face Brush Round & Flat [HB1258]

The bristles pop out from the tip of the brush when the cap is inserted from the bottom of the handle, allowing you to open and close the brush as needed. The moderately resilient bristles of this powder and blusher brush enable you to achieve a seamless finish and deliver powder to the contours of your face.
