Sharpie, the, erm, sharpie company, has just reinvented the genre. Instead of making an erasable pen, it has made a non-erasable pencil. How’s that for smart thinking? The Sharpie Liquid Pencil contains an “ink” made from liquid graphite and lays it down just like a pen. Once written, you have three days to think on the validity and weight of your words. During this period you can erase it just like pencil-marks. After the three days is up, the pencil lines will turn to ink and remain inscribed forever.
Very cool. Will need to get a bunch of these for the office.
