These soft, smooth, velvety pencils can be mixed and blended to create an infinite spectrum of rich, vibrant colors. They're ideal for a wide range of drawing styles, from bold contemporary still lifes and portraiture to finely detailed work — fashion illustration, animal portraiture, and landscapes. The unique formulation is highly blendable and glides smoothly over a wide variety of drawing surfaces. They are acid-free and tested for lightfastness. Pencils are pre-sharpened.
