Glow in The Dark Pigment Powder for Slime Luminous Powder 12 Colors (0.35 oz Each) Safe Non-Toxic,DIY Slime Supplies Set for Nails,Music Festivals,Resin,Concerts,Halloween

Pretty good glow! I mix with floetrol and water for my paint pours. Can be messy, have containers or clips nearby to close the envelope with the powder inside.

Love love love this stuff. I used it to make glow and the dark paddles. Not only does it work with a normal light, if you put it in the sun for a bit the glow is even more impressive. I am super pleased with this stuff

Used these to make slime for my daughter's Glow In the Dark bday sleepover. We made the slime during the day and let them sit in the sun inside their air tight deli containers. That night the kids played with it as it glowed.Perfect GID party favors!

My slime queen daughter said this was the best ever!! She makes more slime than anyone I know, and has used various pigments in the past. Said this one rocked!

Perfect for what I was needing! These are very bright and true to color when placed under a very bright light for a while. I will definitely be buying more!

You could tell the glow powder was mixed with nonglow powders in each packet. Not 100% glow pigmented

I was a little disappointed with this purchase sense only 3 of the 12 actually glow in the dark... I left all the colors under lights in the Sun anywhere where they could get lots of light for a long period of time and they still didn't glow... The rest of them are just neon colors

These are great colors!!! they illuminate really well. I will but more!!! you will not be disappointed if you get these folks :)
