Glow in The Dark Powder Pigment with Flashlight, 120g Luminous Powder Dye Set, 20 g/0.7oz Each, Neutral and Fluorescent Colors for Various Activities, Evening Parties, Halloween, Nail Art, Crafts

I mixed the green and blue with epoxy and they worked better than I expected. The pink is more orange, and the purple only has a very faint glow. It only takes a few seconds to charge up and lasts about 15 minutes. No complaints!

Awesome product. It goes a long way and glows very brightly. I used it for a resin dragon egg night light and it glows for a pretty long time

I wasn't even sure if it would really glow especially when mixed in with epoxy. It was way better then I ever expected. It glows and it's very bright and vibrant. The amount of time the glow lasts is what really surprised me. The brighter the light, the longer the glow. They also send a little instruction book and a complimentary flashlight. (Batteries not included) The only heads up from me is something they mention in the little book too. When you mix it in with whatever your using it with make sure you really mix it good otherwise it will clump at the bottom. Other then that it's so cool. Thanks guys.

Not very bright when glowing but better color then expected

These are wonderful! The glow is bright and you get a lot of product. The bottles are a good size since a little goes a long way. Easy to use. I suggest buying a small blacklight or LED flashlight to intensify the glow
