Sharpie Liquid Pencil. If you'll recall, the Liquid Pencil first increased nerd heartbeats around the world a week and a half ago, when it was launched promising to write like a pen, erase like a pencil, and eventually dry like a Sharpie permanent marker. In fact, those were Sharpie's exact words: "Becomes permanent like a Sharpie marker after three days." The world seemed yet full of wonder; our ambition was limitless. We poured champagne and conducted our first hands-on with great success: indeed, the liquid graphite contained inside wrote like a pen and then erased completely. A simple pencil rising to the pages of Engadget -- could any story be more American? But then... tragedy.
A week later, we returned to our Moleskine to test the permanency of our earlier scribbles and found that they still erased completely. Yes, given enough squinting and optimism, the argument could be made that the marks were slightly darker, but we'd been promised "permanent like a Sharpie marker" -- was the Sharpie Liquid Pencil nothing more than an elaborate ruse? Our hopes chastened, we clicked off another few moments of film documenting the fundamental transience of our creations, kept our best stiff upper lip, and dispatched a letter to Sharpie, imploring them to explain. Today, we received a response, which we shall reprint in full after the break.
