These Magic Invisible Pens are naked to the visible eye and magically appear when you turn on the attached UV light on the pen over the ink. Your secret messages will not be seen to anyone who lays their eyes on them. The messages can only be seen under UV lighting. The pen can be used on metal, paper, plastic, and even your skin. Now you can leave hidden messages everywhere!
