PRO: make anything glow in black light, CON: if you get it on you YOU glow in black light for days but don't be an idiot like me. Used this to make a costume for a haunt show glow when light is turned on and it works like a dream. The fabric looks normal in daylight nd stage light, but once black light is applied it glows wonderfully. The dye also doesn't rub off which is something I was concerned about. Use at your own risk obviously

Very bright but definitely not permanent on non-skin surfaces
This is very bright under UV and barely visible in normal light unless you know where to look and do so at an angle. My only gripe is that it is far from permanent. On-non skin surfaces, if you rub hard enough with your finger it will rub off, even after weeks of drying. Oh and DO NOT get stuff on your hands or skin. It takes days of washing and showers to get this stuff off. Not that anyone would be able to tell without a UV light though.

watered down
this is the worst UV ink I have ever used, not like others, it is so watered down it is barley visible even with heavy amount used on multiple types of paper that show other UV ink, do not buy from this seller.
