The KIK UV Invisible Ink Pen with a double-ended design combines a UV-reactive invisible ink tip and an opposite tip that functions as a visible marker or protective cap. The invisible ink writes clear, undetectable messages that become visible only under UV light, making this pen suitable for discreet marking, party notes, craft projects and play. The compact, lightweight format is easy to carry and store, and the pen is intended for temporary, light-duty marking rather than permanent identification.
Advantages
This double-ended pen provides both an invisible UV ink point and a convenient opposite tip for normal marking or to protect the UV tip when not in use. The invisible ink remains colorless under normal lighting and fluoresces under UV illumination for quick verification. The pen’s portable size and simple operation allow fast, on-the-go use for creative activities, security checks or recreational purposes. It is a practical tool for short-term, non-destructive marking.

- Secret notes and hidden messages

How to use
Remove the cap from the UV ink tip and write on a clean, dry surface. Allow ink to dry briefly; marks will remain invisible in normal lighting. To reveal the writing, illuminate the marked area with a UV light source and view the fluorescence. Use the opposite tip as intended for visible marking or to cover and protect the UV tip when not in use. Store the pen capped and in a cool, dry place away from direct sunlight to maintain ink performance.
Usage recommendations
Use on paper, cardstock and other non-porous or lightly porous surfaces for best results; test on an inconspicuous area before applying to important items. Avoid contact with eyes and prolonged skin exposure. Keep out of reach of young children without supervision. Not intended for permanent identification or use on critical safety equipment. Replace the cap after use to prevent ink drying.
