Description
Ultraviolet Markers – Blue, Red or Green
Invisible-ink markers that fluoresce under ultraviolet light. Select blue, red, or green fluorescence.
These ultraviolet markers create markings that are inconspicuous under normal viewing conditions and fluoresce under a suitable UV light. Choose blue, red, or green fluorescence to identify property or distinguish marked items. Each selection is one marker, not a three-color set, and the formulation differs by color.
Three fluorescence choices
Blue, red, and green are selectable options. Multiple colors can help distinguish groups of marked items when used with suitable inspection lighting.
Color-specific formulations
Blue and red markers are oil based. The green option uses a water-based formulation and produces lime-green fluorescence.
Mark compatible dry surfaces
Intended surfaces include suitable metal, paper, glass, painted surfaces, and currency. Check the material and finish before marking a valuable item.
Durable markings
The markings are described as heat- and water-resistant for their intended application. Test the actual surface and exposure conditions rather than assuming identical performance on every material.

Choosing & Using This Product
Useful for discreet property identification and organizing marked items for later UV inspection. Allow the marking to dry and verify its visibility with your own light. A small compatibility test is recommended because a marking’s ordinary-light appearance and durability depend on the surface and selected formulation.
Important Use Information
Select one marker color. Test on an inconspicuous area first and confirm compatibility with your UV light.
