This crazy disappearing ink pen is perfect for the James Bond in you. The ink was designed by the KGB during the Cold War in the 1950s/1960s and is supposed to fade minutes after its use.
The disappearing ink pen's ink actually disappears completely within 48 hours of writing. I can imagine this pen being perfect for tricky contracts! This is such a hilarious idea, I'm actually surprised that good ol' James Bond never had one of these for sticky situations -- his tracks could never be uncovered!
