Originally designed for Airbrushing, Magic Airbrush Colours™ have
 great smooth consistency with no particles hovering around. Fast
 drying and easy to clean with just hot water.  If you
 do not have an Airbrush system, you could just use various types
 of brushes to get different results - from covering a cake with 
a thin colour layer to painting as creative as you desire. 
Magic Airbrush Colours™ are glycerin free and will work great 
with royal icing or any frosting, they are concentrated enough, 
so you just need a few drops to reach colourful results.
