Made in Germany from sustainably harvested wood, Staedtler's Mars Lumograph 100 is one of the most iconic pencils in the world. You'll find the bright blue Lumograph at every art school and on the desks of professional artists everywhere. The smooth graphite core lays down dark, consistent marks, and the high-quality wood body sharpens well every time. The core is firmly bonded to the body for superior break resistance. And that thick coat of blue and black lacquer just looks great. We carry Lumograph in grades 6B (softest) to 4H (hardest).
