This is that hard to find UV Blacklight Reactive Invisible Ink for hand stamps, box marking, wall decorations, and other unique security applications. Only visible under black light. Will not wash off easy like other brands, but can be removed with effort. Great for document marking or hand stamping. Glows bright BLUE under blacklight. Kit Includes: (1) 4 ounce bottles of Opticz Brand Blue Invisible Ink, (1) Opticz All Purpose Invisible Blue Ink Marker, (1) 6 inch 4 watt Code 10 Blacklight, (1) Stamp Pad, (2) Rubber Peg Stamps- X's. Best viewed in dark or shaded area with UV light. Normal light (sunlight or white light) can make the effect less obvious to visually detect. Opticz Blacklight Reactive Inks are suited for use on skin, fabric and similar porous or textured surfaces. Please note that the effect is most intense after several minutes as the ink soaks into and dries on the skin. Invisible in normal light and activated with UV Blacklight where it will glow a brilliant bright blue. Ink is waterproof and simple to use. Our UV ink is alcohol based and is very low viscous. The same consistency as water.It is fast drying and won't gum up stamp pads hence they stay cleaner longer. Small amounts of ink used with stamp pad will go a long way. Our inks are formulated to fluoresce brightly under long wave ultraviolet lamps and LED blacklight. Use them for re-admittance at designed events, social gatherings, sporting events, glow parties, marking valuables or your own unique security applications where hidden detection is of benefit. Our inks are non-toxic, fast-drying and non-transferable. This ink can be used for textile marking, hand-stamping, and fabrics as well. If using on skin, avoid application around sensitive areas like eyes and mouth.
