The Skin Tones Chameleon Color Tones Marker Set are perfect for your altered art projects. These markers by Chameleon Art Products Ltd. are better than a normal marker, because they allow you to change color from a light tint to a deep tone! They are refillable, have replaceable nibs and feature double-ended brush and bullet nibs. Try using them on your crafts, graphic and fine art, and manga. Included in the package are five markers (Nude, Sand, Light Peach, Caramel and Burnt Umber). These markers are permanent on most surfaces and are compatible with all other alcohol-based inks.
