## Description

Need to leave a note on someone, but don't want to show it to others? The ink pen disappears so you can do it. A special formula developed during the Cold War Era and now encapsulated in a discreet gel pen for general use. Once placed on the paper, the ink usually displays about 15 minutes. Within an hour, the message will completely disappear and unrecoverable. Even UV rays. Note: The disassembly time of the ink depends on the surrounding conditions.
