This will make it easier to use compressed air to "airbrush" with sharpies. It is designed to connect to standard aquarium tubing. To use this you should connect aquarium tubing to the print, and the other end to canned air (for cleaning keyboards).

I was able to make the canned air to aquarium tubing adapter using Heat Shrink, but I also tried using plumbing tape, both worked fine.

This has really good results for metallic sharpies, and works great with all the colors also. The ornament is an example of airbrushing on glass.

There is a remix of this for Bic permanent markers that I will be releasing soon.
