KGB Disappearing Ink Gel Point Pen

This unique spy pen is based on a secret KGB formula created during the Cold War, and has only recently been adapted to fit the modern gel pen. This is the real disappearing ink spy pen- not to be confused with fabric marking pens or novelty pens that others sell. The ink writes just like a regular gel pen in a dark blue ink, usable with little downward force so no indents are left in the paper. The ink appears normal for about 15 minutes, but will slowly begin to deconstruct itself. Within an hour, most of the ink has disappeared, and within about 24 to 48 hours, the ink will have completely vanished.
