Cretacolor Grey Sketching Chalks

Made from natural and synthetic pigments plus chalk, they offer a wide choice for use in combination or individually. They are ideal for lay-outs in connection with commercial or graphic work, or for rendering the more fluid forms of sculpture shapes or even the more formal, finer shapes, shadings and lines connected with architectural sketches. They are un-fired oil free, and therefore blendable, extendable and soluble in water and must be fixed with a fixative.
