We all know that the fastest way to improve anything is with bacon – or steel. Since writing with bacon just wastes good bacon steel was used when Grand Illusions took on a project of NASA proportions and reinvented the pen. The Inkless Metal Pen is a whole different animal because it doesn’t write with ink, it writes with more metal. Not only does it write in space, in a vacuum, on a plane (don’t tell the TSA we sent you), and on a train – it doubles as a weapon.
