Copic Sketch Markers are ideal for coloring and marking flies - especially foam flies! They can be used for coloring hackles, barring feathers, drawing gills, eyes, or anything you can imagine. The ink is alcohol based and dries completely waterproof. The double ended marker has a chisel point nib on one end and a fine point nib on the other. The nibs are replacable and the markers are refillable which means you will never have to replace the marker.
The Copic sketch markers can even be paired with a specialy designed airbrush system where the markers act as the paint - or in this case the ink. This makes cleanup almost non-existent and color changes are as simple as changing markers. Perfect for quick change small scale airbrushing techniques used in tying flies.
