The quality of Neocolor II Aquarelle Artists Crayons is universally acknowledged. Their excellent lightfastness, their high pigment concentration, and their adaptability to several techniques have helped to 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.Try the sgraffito technique by scraping off one or more color layers to create an engraved effect. Neocolors are soft enough to smudge with fingertips, yet they are much firmer than oil pastels. Best of all, they are water-soluble.Individual crayons measure 105 mm in length and 10 mm in diameter (4-1/8" _ 5/16").Set of 15: White, Black, Yellow, Orange, Ochre, Brown, Vermilion, Scarlet, Purple, Violet, Ultramarine, Cobalt Blue, Turquoise Blue, Emerald Green, Yellow Green
