The Kikkerland Invisible Pen and Light is an invisible ink pen for adults that writes secret messages or passwords. Write your message, wait a few seconds, then shine the pen's built-in light on it to reveal the words.

The built-in LED makes it easy to view and read invisible messages, and it uses a D1 ink refill.
