General Pencil Company’s Sketch & Wash Pencil is two tools in one. On a dry surface, it works just like a traditional graphite pencil. However, when you run a wet brush over this water-soluble graphite, the lines dissolve and become malleable. The water also binds the graphite to your paper so you can add color on top once dried. The Sketch & Wash features a round barrel, matte black finish, aquarelle/water soluble graphite, and is made from sustainable incense cedar.
