Ebay auction text: "Here's something that would make a great addition to any collection of vintage arcade video game memorabilia. It's a Q*Bert pen produced by Eraser-Mate in 1983! There's a small rubber figure of Q*Bert himself attached to the top of this pen, which writes in "eraseable" ink! If you didn't like something that you wrote, you could use Q*bert to erase it. A really cool idea, although using Q*bert as an eraser would probably just rub him out."
