Neocolor II Aquarelle Crayons, excellent lightfastness, high pigment concentration, and adaptability to a variety of techniques have put them in a class of their own.
Neocolor II Crayons are softer than colored pencils, denser than children’s wax crayons, and extremely responsive to a wet brush. Wet and dry techniques can be combined in the same drawing.
Because of their strong pigmentation, light colors cover dark colors and vice-versa . Scrape one or more layers of color to create an engraved sgraffito effect. They’re watersoluble. Individual Neocolor II Crayons measure 103 mm long × 8 mm diameter (4-1/16" × 5/16")
Made in Swiss
Set option : 10, 15, 30, 40 or 84 colors
