Tyrant Skull is a Citadel Dry Compound. 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. This pot contains 12ml of Tyrant Skull, one of 15 Dry Compounds in the Citadel Paint range. As with all of our paints, it is a non-toxic, water-based acrylic paint designed for use on plastic, metal, and resin Citadel miniatures.
