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. 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 store.
