Modern infinity pen made with FSC 100% certified bamboo. Triangle shaped body, one side with CM indication and one side with Inches. Traditional wooden pencils write only up to around 200 metre but this Tree free infinity pencil, has a writing length of up to around 20000 metres using a graphite tip to produce a graphite line. Not only does it write like a pencil, but the markings can be erased. It works by leaving a graphite line on paper just like a regular traditional wooden pencil but it wears down so slowly, that it should outlast up to 100 traditional wooden pencils! With touch tip to operate mobile device. Packed in FSC mix packaging.
