Citadel Dry Compounds are of a thicker consistency than other Citadel paints, which makes them perfect for drybrushing - a handy way to pick out the details on a model, or apply highlights swiftly and easily. All of the Games Workshop paints are non-toxic, water-based acrylic that are designed for use on plastic, metal, and resin Citadel miniatures. One pot contains 12ml of dry paint.
