This 99% pure graphite (carbon) cylinder measures 55mm (2.1 inches) long and 35mm (1.4 inches) in diameter and yet weighs only 100g. Like any graphite, these cylinders will leave marks on the hand or any surface they come into contact with. For this reason they will be sprayed with a coat of clear varnish prior to dispatch. This looks good on any desk. Why not start your collection today or give one to a scientist in your life? We also sell a tungsten cylinder of exactly the same size - but that weighs in over 1 kg!
