The formula is secret – the pencil is world-famous! It was with pencils that STAEDTLER’s success story began. To this very day, first-class materials and manufacturing processes guarantee outstanding and unbeatable product quality. STAEDTLER Mars Lumograph is available in up to 20 degrees – for writing, drawing and sketching on paper and matt drafting film. The super-bonded lead wears evenly and is easy to erase and sharpen. Not only is it an ideal creative companion for drawing and sketching purposes - but also an art-form in its own right. Ever since 1835, STAEDTLER pencils have served both as tools and a source of inspiration for artists, graphic designers and illustrators.
