Dual Action Gravity feed airbrush designed for quick changes of custom mixed colors. The trigger controls both air and colour (down for air, back for colour). This allows the artist to change the width of the line, the range of value and the opacity of paint without stopping their hand motion. Air brushes with top-mounted colour cups in which gravity draws paint into the air brush. Less air pressure is required enabling slower hand movement which creates excellent control for fine detail applications. Perfect for general purpose art and craft projects as well as cosmetics, fingernail art, model railroad detailing, R/C car bodies, and automotive airbrushing.
