Fleet Street DIRTWORKS POWDERS are a coordinated system of colored dirts that are matched to the Skin Illustrator Grunge Palette. DIRTWORKS POWDERS are the safest dirt on the market, as they do not contain any hazardous ingredients such as talc, silica or walnut shells. Use alone or with the Dirtworks Grime Sprays to create a variety of "dirty" makeups. They also blend well with all the Skin Illustrator Palettes and Liquids, Glazing Gels and Glazing Sprays. The DIRTWORKS POWDERS are best applied when using the Dirtworks Dirt Bag. Use Dirtworks Dirt-Tac when only a powdered look is required. Dirt-Tac also helps hold the powders in place.
