This is that hard to find UV Blacklight Reactive Invisible Ink for hand stamps, box marking, wall decorations, and other unique security applications. Slightly visible under normal light or on light backgrounds and brightly visible under black light. Will not wash off easy like other brands but, can be removed with effort. Glows bright RED, BLUE, or YELLOW under blacklight.
Please note the red and yellow are slightly visible under some applications!
Our invisible red & yellow are NOT intended for document marking unless being some what visible is not a concern. These inks are made for hand stamping admission control. If marking documents use our All Purpose Blue! It is totally invisible!
Not sure which color to get? Buy a discounted sampler pack and get a 1oz size of all 3 colors!
