Sharpie Graphite Pencil Ink

Not sure how useful this will be in a world dominated by keyboards, but Sharpie has come out with a pen that has “liquid graphite” ink, as in pencil graphite. It writes like a pen, but the graphite ink is erasable for up to three days. One good application would be contract writing on the fly…. maybe, I don’t know. Or note taking in class. $4.99 at Office Depot Source: The Daily Wh.at
