ArtGraf Drawing Putty encourages complete freedom in mark-making. It is a soft, malleable putty saturated with graphite that can be constantly re-molded to draw in new and inventive ways. It is also water soluble, allowing it to not only be worked in a multitude of ways but create a vast range of tones and densities of graphite. This allows artists to blend, sketch, smudge, create washes, opaque blocks of tone and everything in between.
