Description Item # SPM12452648919 Model # KGBDIP
Need to leave a note for someone, but don't want to them to be able to show anyone else? The KGB disappearing ink pen will allow you to just that! This special formula was developed by the Russians during the Cold War and is now encapsulated within the discrete gel pen for general use. Once on the paper, the ink will appear normally for about an hour. Within 2 to 4 days the message will have completely vanished and will be unrecoverable; even with ultraviolet light! Note: deconstruction time of the ink will vary depending on ambient conditions. Warning: never use on any legal document or financial instrument.
