Derwent XL Charcoal combines the natural qualities of charcoal and traditional drawing colours with the strength and body of a chunky block. Derwent XL Charcoal is very opaque. Offering from powerful lines to subtle gradients they feel soft, smooth and velvety, similar to a soft pastel. Derwent XL Charcoal can be layered easily over one another to create the perfect blend of rich tones and organic marks.
