The quality of Neocolor II Aquarelle Artists Crayons is universally acknowledged. Their 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. Best of all they are water soluble.
