Created by San Francisco artist, Agelio Batle, these functional graphite pencils allow you to bring an artistic touch to your everyday life. All items are made of graphite, the same material as normal pencil lead, but treated with a polymer that helps prevent the staining of hands. All graphite pencils wear very slowly and will last an average of 7 to 9 years of everyday use. These functional pencils make a great gift idea for practically everyone.
