The invisible ink pen with UV light.
Get your spy on and write some secret coded messages that nobody will be able to read without a UV light with this badass invisible ink pen.
It’s dead easy to use.
To use the device just write your secret message on a piece of paper with the pen like you would any ordinary pen and then when you are ready to reveal the message switch on the hidden in built UV light and you’ll suddenly be able to read the message.
The invisible ink pen weighs 3.2 ounces and measures in at 6 inches x 2 inches x 8.5 inches in size.
The invisible ink pen is a damn cool novelty toy and it’s also an extremely affordable one costing just over $10 bucks which we think is a total bargain.
We’re giving this one two thumbs up!
