Tree free infinity pencil

This Tree free infinity pencil replaces your traditional wooden pencil. Traditional wooden pencils write only up to around 200 metres, but this Tree free infinity pencil, has a writing length of up to around 20.000 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 just like a regular traditional wooden pencil graphite line on paper, but it wears down so slowly, that it should outlast up to 100 traditional wooden pencils!
