The Iwata Custom Micron CM-C (Version 2) airbrush features a slightly larger .23-mm nozzle and is ideal for use with paints that are too heavy for a .18-mm nozzle or when larger work is being created. The Custom Micron CM-C features a larger 1/3 oz. (9 ml) gravity-feed color cup for working with larger volumes of paint. the trigger is square shaped to be more ergonomic, the crown cap fits on the back of the handle in the crown cap dock (so you don't lose your crown cap!) and the auxiliary lever is now attached to the chucking guide for easier re-assembly.
