Description
Write secret messages in invisible ink and reveal them with the included UV light! This three pack contains red, blue, and green Gelly Roll pens. The ink is clear and nearly invisible under normal light. When the UV light is activated the colors glow. Each pen has a 1mm tip that draws a 0.4mm line. We recommend trying different types and colors of paper for a variety of fun effects. The UV light comes with a keychain attachment!
