This neat pen makes "for your eyes only" messages that can be revealed with the included black-light cap.
2 Invisible ink pens. The caps contain powerful 'black-light' beams which reveal secret messages.
The invisible ink contains special high brightness ultraviolet viewable compounds. The ink is completely invisible in normal light. The secret messages can only be revealed by the beam of the UV 'black-light.' This beam consists of ultra-violet energy close to the visible spectrum of light which causes particles within the ink to 'fluoresce,' illuminating the message.
Not intended for children 3 and under.
