FM Radio Pen

Product Detailed Description

Some notes are not meant for every reader. A slim invisible-ink pen lets the user jot a private message on paper, metal, plastic or even skin, then shine the built-in light to reveal it — all in one discreet instrument that slips into a pocket unnoticed.

Combining the light and the invisible ink in a single barrel keeps the idea simple: write first, uncover the message later. Because the pen behaves like an ordinary writing tool, the hidden text stays out of sight from anyone nearby, which makes it a natural fit for party games, secret notes, security-style marking and novelty gifting.

For distributors, the barrel offers room for a brand mark, and the novelty of hidden writing gives recipients a reason to keep the pen on the desk instead of losing it in a drawer. It suits trade show handouts, client thank-you sets and gift-shop shelves alike.
