Blend multiple tones with one Chameleon Color Tone Pen. Create smooth blends, shading, highlighting and 3D effects just by adding tone to the marker color. A special mixing chamber holds toning medium that infuses onto the marker tip. Add a little for tones, add a lot for color tints. The ink is professional quality, alcohol based, low odor, non-toxic, and permanent on most surfaces. Marker pens are double-ended with both a SuperSoft Brush Nib and Bullet Nib. Refillable, and all nibs are replaceable.
