Polychromos colored pencils have unsurpassed lightfastness. They have a buttery smooth color, are easily blended and layered without waxy build up. The thick 3.8mm leads are break and water-resistant, smudge-proof and provide permanent, rich color.
Derwent Inktense are lightfast, water-soluble ink stick pencils that can be mixed with water to create colorful, fluid, ink-like effects. Once dry they resemble Sumi ink brilliance, will not dissolve, and other media can be applied over the color.
