Chromatics is the science of color, and this Tornado will take your visual perceptions to a scientific level with its vibrant rainbow finish. The spectrum of colours are ion-plated on the barrel, then lightly brushed and complete with polished chrome. Each barrel will have its own unique color variation from one pen to the next, but they all are loaded with a smooth rollerball refill and packaged in Retro brand packaging. This Tornado Rollerball and Propelling Pencil will take you to another world where waves of color stimulate not only your eye and brain, but now your writing too.
