Koh-I-Noors Progresso Woodless pencils are unique solid color lead sticks with a lacquer coating. They have a pleasantly weighty feel and contain a wide range of dense, evenly dispersed pigments that lay down easily. They work beautifully in delicate layers or in heavy strokes, and because of the softness of the lead they blend extraordinarily well. Since there is no wood casing, woodless colored pencils are excellent for precise artwork as well as broad, loose strokes, and shading work. They can be sharpened with a traditional pencil sharpener, and the shavings can be used for smudging in color. 24 assorted colours.
