Koh-I-Noor�s 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.
A proprietary blend of oils, binders, and premium pigments are used in every line of Koh-I-Noor colored pencils. The result is an ultra-smooth lead that allows for rich color and laydown without a waxy bloom or wax build up that prevents layering. Koh-I-Noor uses California cedar for all of their artist-grade colored pencils. California cedar is not only a renewable resource, but is regarded as the best wood for pencils because it doesn't warp. Woodless pencils have a solid color core encased in lacquer, and offers the artist maximum color laydown.. All of Koh-I-Noor pencils come pre-sharpened.
