They say that the pen is mightier than the sword, but is it superior to the bullet? I suppose if you are at a standstill, you might as well aim for the middle ground – and that would mean picking up the $24.99 .375 Bullet Pen. This pen that resembles a powerful bullet might eventually end up as the most powerful weapon (other than the Death Star, of course) in the known universe, when placed in the right hands. It uses a real .375 H&M Magnum Shell, which of course, remains inert. It is able to write in temperatures from -50º to 250ºF, underwater, in zero gravity, and even at any angle. I would not want to bring this to the airport with me though, as it might cause unwanted hold ups at security checkpoints.
