Derwent Studio Pencils If you like the texture and blendability of Artists colour pencils, but prefer a crisper, more precise drawing style, the pencil is for you. Studio shares the same colour strips as Artists, but it is slimmer and the woodcase is hexagonally shaped rather than round. The result? A colour pencil that is easy to grip and particularly suited to detailed illustration work, such as botanical studies, architectural drawing and graphic design. All tend to be studio-based - hence the name.
