UV Cipher Spy Pen

Mark your valuables with your name or a number only you can see. Create some cool body art for your eyes only (or the eyes of anyone you choose to show it to). Write a secret message that only someone with a UV light can read.

This cool UV pen writes invisibly. The naked eye can't read anything you write until you shine an ultra-violet light on what you've written. They're great for marking valuables without engraving them, or making secret notes.

UV pens were recently shown in the feature film Paul Blart: Mall Cop. We don't recommend you attempt a mall heist and use the pens to write down credit card codes like in the movie, but they can still be used for lots of cool things!

You get a keyring UV light with your neat invisible pen?and 2 refills that will last a long time.
