Glow in The Dark Pigment Powder - Epoxy Resin Colour Pigment Dyes for DIY Slime Colouring Kit - Luminous Skin Safe Long Lasting Self Glowing for Acrylic Paint, Nail Art, Painting, Crafts - 0.4oz Each

I really like these powders. They mix in well and the colours I have used come are nice even without the fact they glow in the dark. You do have to charge them with light, as with any glow in the dark product. My sister’s friend told me they are rubbish, but she keeps hers in a cupboard so they never gather any light to make them glow. Maybe the manufacturer could put a note in to that effect for people who don’t have experience of things that glow in the dark like these. I have used them in fridge magnets and a trinket pot. The colours come out really well in the casting. The colour of the pigment isn’t necessarily the colour of the glow. I made some letters in various colours and a pot with pink glow pigment and the glow is yellow, but it Looks really cool. I will definitely be buying more of these when I run out. It doesn’t take loads to get a good glow. The pictures are of my first attempt. Not all the letters have glow in the dark pigment in, and I had only quickly held my phone torch over them for a couple of minutes to see if they had worked. All in all I like them.

Strong colours that shine well in the dark-once activated by exposure to light.

I took a chance after seeing some negative reviews and I'm glad I did because this stuff is so bright when it glows that Even the picture I took nearly blinded me.I personally think alot is down to user error as I was not stingy when adding pigment and I have loads left still.

I've used these powders expecting the extraordinary. While the results are pleasing and different do they glowin the dark? no.

Some of them show up very bright like the green and stay glowing for a long-time however others do not show or last as long

The media could not be loaded. This product is amazing. The only draw back is my package didn’t come with instructions on how to activate the glow. Until I accident left the lamp on beaming at th terrarium and a few hours later in the middle of the night I walked into a glowing amazing light. I have now bought the bigger size . Just amazing

Easy to mix, the pigments leave a very light colour in daylight but the glow is definitely there in the dark. You think there's not a great deal of powder in the packets but you need it to drop to the bottom so you don't inhale it. You don't need a great deal either. My bears are made with resin.

Have only really tried one of the blue ones in UV resin, mixed in well, nice colour, and glows in the dark. What more could you want. The green one glows the brightest, but all can be seen in the dark.
