Glow in The Dark & UV Reactive Powder - Multipurpose PRO-Series (Natural Green, 2 Ounces (57g))

This powder glows VERY bright! It is incredible, I stuck the bag under UV light for 30 secs after I recieved the package and took the first picture. Its glowing bright enough you can see the details of my hand. But, I bought this to add to a 3d resin printing project. The particles are too heavy, instead of being suspended in the resin evenly the glow powder sinks to the bottom of the vat. The first few layers of the print will lift the glow powder, but everything underneath won't get any powder after that. So the first few layers of the print will glow super bright, but the rest of the print will only have a small amount of powder. In my particular case this worked out, because I only needed one side of the print to glow, you can see in the second picture the top glows brightly, but the middle and back are really only being lit up by the glow from the top layers. If you are looking at this and thinking about adding it to a resin print, I would suggest looking for a different solution. Finding a powder with a finer/lighter particle size would be ideal, but thats not really info that many manufacturers release. Personally I will be trying glow-in-the-dark alcohol based inks next, as well as picking up some premixed glow resin. If you are still thinking about this for a resin print (Good for you! Experimenting is fun!) then I have one last bit of advice: make sure you have a fresh FEP film on hand, because this powder will scratch up the film in your vat. Also don't dump the powder contaminated resin leftovers back in the bottle, it will contaminate the whole bottle. Probably shouldn't put it in your resin left-overs bottle either, just try to keep it seperate from everything else really. So 5 stars because it is an insanely bright glowing powder.

Charge quick and bright longer. The powder mix well in the resin. Under UV light 15 to 30 seconds the brightness last for several minutes. The shine go to zero after several hours. I have tried with several but so far this is the best.

Bought last year. Used on several items for easier access in the night. Works! Mixed with nail polish , it's ok though not an attractive look. Hoping to find a better format/ formula for future uses.

Bought this for sand art and to put in slime. My nephew loves it! It does glow really well. It’s bright yellow/green. So easy to use, just pour into whatever craft you are doing! Great quality, and amount for an affordable price. It comes in a thick plastic bag, that is durable and holds up to an enthusiastic 7 year old. The size of the bag was fair, although I’d prefer it to be a bit bigger.

This stuff works...I got the green, but wished I got white to mix in my own mica colors. After just seconds of strong light exposure and a 1/8 of a teaspoon, the bars of soap light up like Christmas trees! This small bag would make pounds of soap, so if that's your use...get white, because even mixing in mica and glitter, it glows super bright. A definite must have for experimental soap making.

this stuff really works well. mixed with matte gel medium (and later with acrylic paint) to decorate plastic skull and it's amazing how bright it can be. one issue is it really needs to be exposed to light quite well so think about how you're using it. takes some work to mix smooth. a little goes a long way. would order again as it's better than any glow-in-the-dark paint I've ever used.

I bought 4 ounces of this Glow In The Dark Powder which is a fairly large Amount! It's enough to fill the entire palm of your hand with some still left over. This Glows Extremely Bright and Last for about 5 to 10 minutes when charged with a Black Light Flashlight (which, happens to be Longer than Most glow in the dark powders.) It Actually Glows Brighter than Any other black light product I've ever bought which, makes me Happy with my purchase!

I got these to mix in to paint or glue to put on a derby car. It worked for the most part. I expected it to charge in the sun all day then glow all night, but it didn't happen. It has a short charge period where it's clearly visibly glowing after the sun goes down, but that's usually as the sun sets. By the time it's fully dark, you can barely see a glow. It will recharge for a few minutes with a flashlight, but not long. It's still cool though. I mixed it in a clear top coat nail polish and it made my nails glow. For the car, I mixed it in mod podge and put it over the paint.
