Secret Notes Pen + UV-Lamp

The Secret Notes Pen + UV-Lamp combines writing and concealed message play in one compact format. Hidden notes appear only when the integrated UV light passes over the writing, so each message can shift from an ordinary blank-looking note to a readable clue, answer, or secret line in seconds. The pen uses a simple mechanism that is easy to understand: write the message first, then shine the UV light over the page to make the text visible. That clear two-step action gives the set its appeal for coded notes, mini treasure hunts, and message swapping. The data states 2 batteries are included, so the light function is part of the pen's ready-to-use setup. The age marking is 6Y+, which fits the straightforward writing format and the visible reveal effect. On a desk, in a notebook, or during small game moments, the pen supports quick rounds of hidden-message play without extra equipment. Short clues, names, and secret reminders can be written, concealed, and checked again with the same pen, keeping the activity focused on writing, revealing, and reading back the result.
