The Flame and Smoke special damage markers are sold as a set. They simply slide over the top of one of the official flight pegs.
Flame Marker
The flame marker is laser cut from 3/16 (5mm) orange plastic. It has some detail etching on it to allow you to color it in with a crayon. I suggest using red to give the flame marker a little more visual appeal.
The smoke marker is laser cut from 1/8 (3mm) tinted plastic. It also has the detail etching on it. The tinted gray color give it a nice smoke look to it.
For those that might be interested, here are some shot of the development process for these.
Initial sketches
Paper prototypes
I personally took the time to paint my flame and smoke markers to make them look even better...
And a few shots of the markers in games.
