Frequently Asked Questions

How do these invisible ink markers work?

The markers contain clear fluorescent compounds that absorb invisible ultraviolet radiation and re-emit it as bright visible light. Simply write on paper, wait a few seconds for it to dry, and turn on the UV LED light located on the pen cap to inspect the glowing message.

Can the message be seen in ordinary room light?

No. Once dry, the ink is completely invisible to the naked eye under standard sunlight or interior room lighting, leaving zero tint or gloss behind.

Are the UV lights battery operated and ready to use?

Yes, every marker cap comes complete with pre-installed button cell batteries. Simply press the switch on the cap to project the UV beam.

Is the ink washable from hands and fabrics?

The mild water-based formula washes off skin easily with warm soap and water. On non-porous surfaces like glass or glazed ceramics, it can be wiped clean with a damp cloth.

What surfaces work best for secret messages?

Standard white or light-colored unlined notebook paper, index cards, and cardstock offer the highest contrast and most dramatic fluorescent glow.
