Invisible Ink - Basic Pen

This Invisible Ink - Basic Pen is a pen that works with invisible ink. When writing with this pen, it is not visible to the naked eye. The moment you shine a UV lamp on the ink, the written text becomes visible. When you have written a text with the pen or want to read someone else's text, you can use the UV lamp on the back of the pen to make the text readable.

Operation of the pen:
The Invisible Ink - Basic Pen comes complete including batteries. When the pen is removed from the packaging, it is immediately ready for use. Between the batteries in the pen is a small piece of plastic that you must first remove before the UV lamp works. This is to protect the batteries so that they do not run down. When you have written with the pen, you can turn on the UV light at the top of the pen by means of a button.
