ArtGraf Watercolour Discs come in the handy shape of an old-fashioned tailor’s chalk. The tapered edges and rounded corners can be used for line work and details. The broad side can be use to create large bold strokes. The intense black is water soluble, too. Try carbon stick on wet paper for a delicious drawing stroke. Figure drawers will love the ease and versatility of this uniquely shaped drawing tool. Also available in sets.
