Our special made blend of invisible red UV Blacklight Reactive Invisible Ink is ideal for hand stamps, box marking, secret messages, escape rooms, retail operations, ticket marking, admissions, and other unique security applications. Adheres and sticks to any porous surface with ease. Will not wash off easy like other brands. Very difficult to remove.
Please note ink may be partially visible on high white surfaces. Application on off white to medium base will make the ink less noticeable. Conceals best and completely when applied to skin. Water based mixture is skin safe. A very light application is all that is needed to get outstanding UV blacklight effects. Please allow time for ink to completely dry. It will initially appear bright pink, but will take on a deep red hue once completely dry. Highest luminosity in blacklight occurs after ink is no longer wet.
Not for printers or tattoos!
