Innovative, environmentally friendly and with a unique and original design: Perpetua is round with a single flat side. We invented it, all you have to do is choose the colour of eraser you like.
It is different from all other pencils:
  
it writes for 1120 km, 22 times longer than a traditional pencil;
  
the design is unique and unmistakable; it has only one flat side, for the rest it is round;
  
it is made of Zantech®, an innovative material composed of 80% graphite recovered from industrial processes;
  
it can be sharpened, but it also writes without a point or if split in two;
  
it lives together with its eraser without any use of glue;
  
if it falls, it does not break without the use of paint or wood.
  
100% Made in Italy
