UV Invisible Marker Pen

The Ultraviolet Marker Pen Ink can be seen when exposed to ultraviolet light.

The marker fluorescent ink is totally transparent and colourless and remains invisible regardless of the substrate type and background colour.
It's undetectable and doesn't leave white streaks.

To reveal invisible ink messages made with the fluorescent marker, simply use an ultra-violet light source using a wavelength of 365-395 nanometers (invisible and visible light).

The writings made with the fluorescent marker will appear blue and highly luminous under UV light.

Composition: solvent-free, non-hazardous marker.
