Everything about Derwent XL Graphite is big; big blocks & even bigger possibilities. You will find you can create a wide variety of textures & effects with these generous graphite blocks; subtle blending, fine lines & deep tonal work are all possible. The graphite is water-soluble too so that means even more possibilities! We have developed 6 dense shades from Olive Green to Burnt & Raw Umber which work really well for bold landscapes.
