4 PCS Invisible Fix Magic 2 in 1 UV Office Dick School Supplies

You generally don't see the world written with an invisible pen unless you use the UV light that is part of the pen.


People often use these markers as a secret tool for writing love letters, or for securely entering passwords, recovery seeds, and other secret texts that you do not want anyone else to read.


You can decorate your face or body with a marker to stand out, for example, at a disco with UV lighting.

Can be used as a micro flashlight at night.
