Invisible Ink Secret Message Pens with UV Light

Create hidden messages, clues and drawings with this 12-pack of invisible ink pens featuring integrated UV reveal lights. The special ink appears invisible or difficult to see under normal conditions and can be revealed by illuminating the writing with the pen's UV light, adding an interactive element to notes, puzzles and games.

Ideal for treasure hunts, secret-message activities, party games and creative play, the pens allow children and adults to exchange concealed notes or create clues that only become visible when viewed under the supplied UV illumination.

Their compact marker-style format makes them easy to use at home, school activities or parties. With multiple pens included, the set is particularly useful for group activities, party prizes, treasure-chest rewards and gift bags.
