Colorless Fluorescent Marker Pen

This pen writes invisibly under normal lighting, then reveals a bright fluorescent glow when exposed to ultraviolet light. The pen body is crafted from environmentally friendly AS and PP materials, giving it a lightweight feel while remaining durable for everyday use. The smooth pen tip delivers consistent ink flow for effortless writing without skipping or blotting. Under standard lighting, your writing appears completely invisible, and leaves no trace on paper, making it ideal for secret messages, fun graffiti, anti-counterfeiting marks, or exam anti-cheating notes. When you shine a UV light on the page, the hidden text pops in vivid fluorescent color. The ink is safe and non-toxic, suitable for all creative scenarios including office and study use. The barrel and cap feature a built-in pocket clip for convenient attachment to notebooks or pockets. 5.35" L
