High grade Daytime "Invisible" ProFX Glow in the Dark Acrylic water-based pigments that glow brightly in the dark. NOW available in 7 colors!. Strontium based rare earth elements, these pigments are NON-TOXIC, and have the brightest longest glowing times available. These versatile Glow in the Dark pigments are made from the purest product available and have a glow life span of over 10 years. What makes our pigments glow brightly is their crystal formation, just like small batteries they charge and discharge their energy. UV rays from Sunlight or even Black Light UV will supercharge these pigments, incandescent and LED takes a little longer. We have everything from super fine to a coarse sand. All ProFX pigments are structurally designed to be mixed with clear mediums, Acrylic, Epoxy, Glues and even Slimes. Do not mix other types of colored paint as this will stop the crystals from charging and emitting their glow. We do sell our airbrush and thinning medium through our Amazon store.
