The Iwata airbrush uses compressed air to atomize paint or other media into a fine mist. An airbrush consists of a trigger mechanism that controls the flow of paint, a nozzle that shapes the paint stream, and a small reservoir that holds the paint. By pressing the trigger, compressed air flows through the nozzle and pulls paint from the cup, creating a controlled spray pattern. Airbrushes from Iwata are known for their precision and detail in a wide range of applications.
