The crown cap allows you to get closer to your work and thus achieve finer detail, whilst still protecting the needle. It also decreases paint build-up on the needle and in the nozzle cap, preventing spitting.

A crown cap replaces the needle cap. It physically protects the needle while spraying very fine lines. It also prevents pigment build-up and spattering when spraying large backgrounds.

Both of these benefits are obtained due to the better air displacement provided by the cut away sections of the crown cap.
