Invisible Pen with UV Light

Product Detailed Description

Secret notes take on a new life with this slim invisible ink pen that hides its writing until a built-in ultraviolet lamp brings every word up in bright contrast. Slip it into a party bag, an escape room kit, or an office gift exchange, and the light-play hook does the rest.

The barrel writes with clear fluid that looks blank on paper, while the small UV lamp housed at the end of the pen reveals the hidden message with a quick pass across the surface. Measuring 136 x 16 x 10mm, the pen keeps a comfortable everyday grip and fits neatly into pencil cases and novelty displays.

Three AG3 batteries come included, so the fun starts straight out of the pack. Quietly effective for classroom rewards, spy-themed assortments, and promotional giveaways alike, it pairs well with other message pens on the shelf.
