Our proprietary blend of invisible blue UV Blacklight Reactive Invisible Ink is ideal for security marking, merchandise tracking, coding, 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. Avoid using on a surface that already glows in IUV light (like most common printer papers) as this will greatly dull or even cancel out the blacklight glow. Conceals best and completely when applied to skin. Water based hybrid 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 as this is when the best UV effects will be visible.
Not for printers or tattoos!
