Invisible Ink Pen
Everybody has their secrets. What do you do when you want to write a message that only certain people can read?
With this Invisible Ink Pen, now you can easily take care of even the most top-secret of messages all without ever seeming suspicious at all.
Write your message with the invisible ink, and under normal lighting, it will look as though the page is completely blank.
The message will only be revealed when you or your recipient shines a black light on the paper to make the invisible writing pop to life. This is a great gift for kids and adults both.
