The KGB Pen from ThinkGeek “features a special gel ink developed by real KGB scientists during the Cold War (and made in Russia), that disappears completely — it will be completely gone within 48 hours.” Video after the break.

And not just faded – gone! Even UV scanners won’t be able to detect that anything was ever written with the KGB Disappearing Ink Pen. Spies need the best (you need the best), and the KGB Disappearing Ink Pen is the best there is.
