A never-ending pencil and a work of art? Named after - and inspired by - the award winning Pininfarina Cambiano concept car of 2012, the pencil takes several design cues from the concept, notably the sleek lines and inset wooden detailing.

Using a clever and patented metal alloy tip (Ethergraf®) to produce a precise, graphite-like line, the Pininfarina Segno Cambiano writes like a hard pencil, and its markings - which are lighter than a normal pencil - can even be erased like one. Like a pencil, it works by leaving a bit of the 'lead' on the paper, but the metal alloy wears down so slowly it should last for a lifetime of use.

All Pininfarina Segno Cambiano pencils are made entirely by hand in Italy.

The sleek body tapers from the middle of the pencil to each tip. Measures 160mm long, barrel diameter ranges from 10mm at its widest to 4mm near the tip, weighs 38g.

Supplied in a wooden presentation box which also doubles as a decorative yet functional desk stand for the pencil.
