Badger Air-Brush Company Stock Number 50-0173 Fine Needle for Model 200 (gravity feed only). The Model 200 internal mix airbrush has a needle that runs through the length of the airbrush. When operating the airbrush, the needle retracts into the airbrush, controlling the flow of paint. The needle is made of a precision manufactured durable stainless steel, machined to a sharp tip. Avoid dropping the airbrush, as a bent tip on the needle will compromise the spray pattern. Badger Air-Brush parts are proudly made in America.
