About Perpetua Graphite Stick - Classic Collection Perpetua - pure Italian ingenuity! Manufactured from Zantec®, an innovative material made from 80% waste graphite particles (15 grams of them per stick to be precise!), combined with an inert and safe patented chemical compound. It is clean and does not rub off on the hands so does not need a protective wooden sheath like normal pencils, it is incredibly tough so will not break if dropped and lasts almost forever. This stylish graphite stick writes with the equivalent of an HB grade, can be sharpened with a standard sharpener (although you won't need to often!) and has an integral eraser which comes in a choice of 10 different colours. Non-toxic so safe for both adults and children, and can be used safely in operating theatres and on board spacecraft as graphite micro-particles do not disperse and short-circuit electrical instruments. It even has one flat side to prevent it from rolling away!
