Abstract: An airbrush has a housing with at least two air chambers. Each chamber is sized to receive a nib of a pen. A motor is oriented in the housing. An air pump is oriented in the housing and is driven by the motor. The air pump is in fluid communication with the at least two air chambers for forcing air into each of the at least two air chambers, about each pen nib to entrain particles from the nib into the air, and out of the housing for providing a combined spray with particles from pens of the at least two air chambers.
