The Iwata Custom Micron CM-B features a 0.18-mm Matched Head System. For extremely fine detail, it will spray a Micro-Line to a 3/4 inch wide swath. It comes with a Pre-Set Handle, Adjustable Main Lever Tension, Crown Cap and a 1/16 oz. (1.8 ml) Gravity-Feed Cup. This new improved model of the CM-B features a square shaped trigger to be more ergonomic, the crown cap fits on the back of the handle in the crown cap dock (so you donÃ†t lose your crown cap!) and the auxiliary lever is now attached to the chucking guide for easier re-assembly. It comes in a very nice metal case.
