Just in!!! The Invisible Ink Pen
Just received a small shipment of invisible ink pens. It comes with a built-in UV light in the cap so you can view the ink with the writing instrument itself. The ink is really easy to read, even in broad daylight when you use the UV light to view the invisble ink. A very practical use in the invitation world is to number your RSVP cards so guests can be identified even if they don’t remember to fill in their name or they do not write legibly. What would you use this pen for?
