Iwata Hi Line HP-CH 0.3mm Featuring the ultimate in air control directly at the nozzle with Iwata\'s new Micro Air Control (MAC) Valve Technology, this Hi-Line airbrush is designed for artists who need extreme control of detailed spraying, this brush uses larger diameter threads on the 0.3-mm nozzle than the High Performance Series. This makes the nozzle much stronger when tightening it onto the airbrush and ensures better centring of the nozzle when it screws onto the airbrush body. This Hi-Line Series brush is now made with PTFE solvent-proof needle packing, a dual-purpose cutaway, pre-set handle and one-piece auxiliary lever/needle chucking guide and comes with a large 1/3 oz (9 ml) tapered gravity-feed cup. The larger nozzle and needle makes this an ideal airbrush for spraying a variety of paints from watercolours to solvent-based automotive paints.
