HOW TO APPLY: Brush On Block is housed in a self-dispensing brush applicator. The powder flows through the brush and onto your skin when applied. When you receive the brush it will be in the "closed" position. To open, twist the bottom cartridge slightly to the left, about 1/2", until you feel a slight 'click'. Remove the outer cap and slide down the protective brush sleeve. Holding the brush horizontally, tap the brush against your wrist or flick the bristles, to get the powder flowing through the applicator. Apply liberally to your face, neck, shoulders, arms and hands.
