With a history dating to the mid 17th century, when Friedrich Staedtler began manufacturing pencils in Nuremburg, Germany, Staedtler Mars is a global icon. The Lumograph drawing pencils are Staedtler's most famous product, sold in every art supply store we've ever visited. There's good reason for the Lumograph's ubiquity. These pencils sharpen cleanly, erase easily, resist breaking, and lay down smooth, dark lines. The tin of six pencils comes with grades HB, 2B, 4B, 6B, 7B, and 8B. The tin of twelve pencils comes with grades 4H, 3H, 2H, H, F, HB, B, 2B, 3B, 4B, 5B, and 6B. Made in Germany.
