Invisible ink pen that allows you to write messages with invisible ink and reveal them with a UV light.
You can use it for diaries, notes, illustrations, and greeting cards to create special effects.
The letters and drawings written with the pen cannot be seen in normal light, but can be clearly confirmed by shining the UV light built into the pen.
It can be used for a wide range of purposes, such as secret notes, playful communication, and simple anti-counterfeiting checks.
