Packaged in tubes of 4 leads, the Shorty Special Edition replacement leads come in 8 colours. Each 7B lead is 3.15 mm thick. These leads can draw/write on almost all materials, including paper, wood, metal and plastic. The red leads can draw/write on glass; the white leads can draw/write on radiographs. The leads taper with use. Thus, it is unnecessary to sharpen them.
