UV Blacklight Reactive Blue Invisible Ink – 8 oz. Bottle
This is that hard to find UV Blacklight Reactive Ink for hand stamps at clubs, box marking, wall decorations, and other unique security applications. The BLUE is only visible under black light. The ink will not wash off easy like other brands, but can be removed with effort. Great for document marking. Glows bright under blacklight. Fluorescent blacklights are recommended over LED or incandescent blacklights for best effect.
Best viewed in dark or shaded area. Normal light (sunlight or white light) can make the effect less obvious to visually detect.
When using, please note that the effect is most intense after several minutes as the ink soaks into and dries on the skin.
8 ounce bottle
Alcohol base for quick drying
