COPIC Marker Airbrush System - COPIC Air Adaptor - Your favorite COPIC markers can easily become an airbrush. Copic markers and Sketch markers both work with the Airbrush System. Simply insert the standard broad or medium broad end of a Copic marker or Sketch marker into the air grip. The air grip can be hooked up to an air compressor or used with a special air can. Changing colors is as easy as switching markers. The COPIC Air Adaptor is an exclusive adaptor for COPIC Air Grip and airhose connection. This acts as the air reservoir to the compressor and provides for even, pulse free, air flow.
