The Space Invaders Secret Alarm Pen. Why would I need a super secret motion sensing pen, we hear you mutter in a polite but bewildered manner. Aha! Why would you not, dear paranoid android, why would you not? $10.98.
Know the moment someone enters your room or office. Intruders never suspect your innocent-looking pen packs sophisticated electronics. When anyone crosses the path of its motion-sensitive electric eye, you get an extra-loud warning alarm. Guard your space when you have to leave the room or work with “eyes-only” materials. Works as a pen too; just twist the barrel.
