Spy Pen

With this Spy Pen you can leave a secret message or make a shopping list. This pen has two types of ink: an invisible version and regular black ink. The invisible ink is readable only if the blacklight is used: this light is on the top of the pen. In addition, the pen has a laser and a small flashlight on a flexible rod. So you can also write with it in the dark. This versatile pen is an asset for anyone who prefers pen and paper to their phone. Works on three LR44 batteries (not included).
