Cool stuff for secret agents!
Pretty cool invisible spy ink pen with UV light - on one end is a pen with invisible ink and the other is an ultravioleth LED flashlight.
A pen that James Bond would be proud to carry in his shirt pocket. One end of the Spy Pen writes with invisible ink, the other end is a ultraviolet light which makes it visible. When your secret messages, codes, diagrams, etc. are written with this pen they will be invisible to the naked eye. The message can only be seen by shinning an ultraviolet light on the seemingly blank sheet of paper.
