This is my favorite brand airbrush that I personally use on all of my cookies. I also love the quality of their stencils and airbrush colors.
If you are looking for an extra gun to go with your Cookie Countess airbrush system then you can purchase a .4mm nozzle gun. The gold tipped .5mm nozzle gun is slightly bigger than the gun that comes with the original system. It allows more room for thicker metallic airbrush colors (or whites) - or for those that like to mix luster dusts with alcohol to make their own color.
