Permanent Invisible Marker

Permanent Invisible Marker: Your Secret Visible Only with UV Light

Mark your belongings or documents confidentially with the revolutionary Permanent Invisible Marker. To the naked eye, no one will notice you've left a mark, but under ultraviolet light, each stroke will glow with fluorescent brilliance.

Designed for maximum adhesion, this marker is perfect for porous materials such as paper, cardboard, fabric and wood, ensuring an indelible mark that will last over time. Need to mark non-porous materials such as plastics, metals or glass? No problem. Although your mark on these materials can be wiped clean, their resistance guarantees that it won't be an easy task.

Whether marking personal belongings, important documents or art projects, the Permanent Invisible Marker gives you the ability to mark with confidence, knowing that only those with access to ultraviolet light will be able to reveal your strokes.
