Opticz invisible blue UV ink is designed to go on invisible and glow bright blue when viewed in UV blacklight. It's a high quality fast drying blend ideal for discreetly marking a variety of surfaces. It's safe for external use on skin when used as directed and will also easily adhere to any textured surface. It's crystal clear in normal light and glows a brilliant blue when exposed to any type of blacklight. This makes it ideal for security and anti theft applications such as marking your personal belongings or marking important documents for quick easy identification later. It can also be used for admissions functions such as hand stamping or any other discreet security application. Opticz invisible blue UV ink can also be used for fun recreational purposes such as UV artwork, escape rooms, glow parties, scavenger hunts and much more.Keep in mind this is a high grade security ink and will not wash off easily. It's designed to stick and stay. On skin heavy scrubbing will remove it to some degree, but natural exfoliation is the only way it completely comes off. It will persist on regular surfaces for extended time as well. While this premium ink is useful for most applications there are some limitations. Please note the ink is very thin and needs a textured surface to adhere to. It's not ideal for use on smooth surfaces like glass or similar. For best results, be sure the surface you're applying it to is not blacklight reactive as this can dull the effects of the ink. Highest contrast when viewed in blacklight is on light colored non UV reactive surfaces. The ink may be slightly visible in normal light if applied to darker backgrounds.  Only a small amount is needed for optimal results. You will receive several useful applications from any of our various sizes.
