Badger Air-Brush Company Stock Number 20-124 Sotar (size 1) Fine Needle, is distinguished by its black plastic end. It produces a Hairline to 3/4-inch (19 millimeter) spray pattern. The Model Sotar 2020 internal mix airbrush needle 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.
