Lyra Rembrandt Polycrayons are a professional range of sketching crayons. Made in Germany, they are of exceptional quality. Lyra Polycrayons are square-shaped pastels with a high pigment concentration, and they can be mixed and blended while retaining their intensity and high light resistance. Use the edges for drawing small details and the flat side of the crayon is perfect for large fields of colour.  With high covering power, the colours apply easily and are perfect for a smudging technique. Each tones set contains pastels in varying shades of black, from grey to white, or varying shades of brown; the soft sets contain a wide range of colour pastels.
