Secret Message Pen

After writing, the message remains unseen until the pen’s built-in UV light is shone over the page, revealing the secret writing and adding an interactive element to ordinary note-taking. Each purchase contains one pen, with the color varying, making it a fun surprise as well as a useful writing accessory. Designed for children ages six and up, the pen can be used for secret notes, coded messages, games, scavenger hunts, and imaginative spy-themed activities with friends and family. The combination of invisible ink and UV-light technology makes writing more playful while encouraging children to experiment with creative communication and imaginative activities. 

The pen contains a button or coin-cell battery, which Scholastic warns is hazardous if swallowed.
