Winrich Aquarelle Pencils have expressive qualities that no ordinary pencil can match. In one pencil, they combine the precision of line drawing with the tonal qualities of watercolor. Water-solubale graphite goes beautifully with conventional graphite, charcoal, or watercolors. Try these pencils on hot press watercolor paper or bristol plate surfaces. Applying a wet brush to a sketch, achieves a rich, colorful effect combining line and tone that's refreshingly different.
