Are you a detective looking for the perfect equipment for your investigations? Our Spy Labs Secret Message Tools are just what you need! You can exchange top - secret messages with your fellow agents using our special disappearing and reappearing ink. With the two secret pens in the set, one pen allows you to write a message that turns invisible once it dries. The other pen can reveal the hidden message and is also used to send your reply. These special invisible - ink pens are great for writing top - secret communications. Tips and tricks for other secret messaging methods are also included. The set comes packed in a durable metal tin, ensuring its long - lasting use.

Using these Spy Labs Secret Message Tools is easy. First, take the pen that writes in invisible ink and write your secret message on a piece of paper. Wait for the ink to dry, and your message will disappear. When you want the message to be read, use the other pen to run it over the area where you wrote the message, and it will reappear. Here are some tips: Keep the pens away from direct sunlight and heat as this may affect the ink's performance. If the pens seem to be running out of ink, try gently pressing the tip on a piece of scrap paper to get the ink flowing. After each use, make sure to cap the pens tightly to prevent the ink from drying out. The metal tin is designed to protect the pens, so always store them back in the tin when not in use.
