Using these Spy Labs Secret Message Tools is a breeze. First, take the pen for writing invisible messages. Write your secret note on a piece of paper and wait for the ink to dry. Once it's dry, the message will disappear. When your fellow agent gets the note, they can use the other pen to run over the paper. The hidden message will then become visible. Now they can use the same pen to write their reply. Remember, keep the pens away from small children as they are not toys.

Also, avoid exposing the pens to extreme temperatures as it may affect the ink.
