Out of the blue
set of 2 secret pens with secret ink and UV light, silver

Chic pen with a twist: At first glance, this silver pen looks like a normal writing utensil. But appearances are deceptive: the secret pen writes with invisible ink! The writing only becomes visible with UV light, which is activated by pressing a button on the pen. This allows you to leave secret messages for friends or clues during a mystery game. A fun gadget for young and old detectives!

Also practical in everyday life: As already mentioned, this pen is also ideal for detective games or escape games, as you can hide messages in an ingenious yet simple way. However, the secret pen is also suitable for everyday use: for example, you can write down passwords and protect them from prying eyes. However, make sure that only you have access to the secret pen with UV light.
