Reddit mentions of Copic CMABS3 Air Brush System Abs 3 Starter Set

Honestly at that age I'd recommend one of those kits that you clip a marker into an airbrush device, Crayola makes one and so does Copic, and I'm sure other companies do as well (fair warning, Copic markers are spendy, about 8 or 9 dollars for a single marker)

Here's the Crayola one

And here's the Copic one

These in general are less expensive and less messy and less complex than a real airbrush system but is good to get a general idea of techniques, using a marker instead of paint that you got to mix to proper consistency and color, easier to clean out and using a foot pump or a can of compressed air rather than a big air compressor which will run a couple hundred bucks on its own.

If she enjoys it and gets the hang of it you can talk with her down the road about upgrading and get an actual airbrush and a mini compressor like this (which is incidentally the one I currently use)

Best of luck hope that helps

I remember seeing Larry Dahlberg talking about the Copic system. It doesn't appear to have all the hassles that conventional systems do. I haven't used it personally, but it looks neat.
