Pen without ink

This infinity pencil with eraser replaces your traditional wooden pencil. Traditional wooden pencils write only up to around 200 metres, but this FSC® bamboo 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 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!
