UV Secret Pen with Torch cap - 10 pack
Here's a neat idea, our invisible pen marker with built in LED light! Great for security marking or just having some UV fun. The pen is filled with our invisible ink formula and will only appear when revealed using the built in UV LED light.
You won't find cheaper UV light on the market. Purple pen surround and the invisible ink glows yellow under the built in LED.
Ideal for kids and fully CE safe
