About Chameleon Pens - 5 Assorted Primary Tones Chameleon Pens are much more than a normal marker - they give you the power to change colour and give simplicity to your art. Each pen goes from as light as a hint of a tint to rich tones, eliminating tonal gaps in your collection. One pen, multiple colour tones! For simple, seamless, colour gradations! Create depth, dimension, highlights, shading and shadows…all with one pen! Built to last, Chameleon Colour Tones have nearly twice as much ink as a regular marker pen. Can also be used like a traditional marker. Professional quality, with alcohol-based ink. Refillable, and have replaceable Japanese Nibs. Permanent on most surfaces (including: fabrics, glass, plastic and wood). Compatible with all other alcohol-based pens and inks.
