Glow In The Dark Pigment Powder 12 Colors Epoxy Resin Dye Luminous Powder Safe Long Lasting for Fine Art, DIY Nail Art, Epoxy Resin Mold Colorant, Acrylic Paint, DIY Crafts and Theme Party, 0.7oz Each

Havent had a chance to use them yet, but with a UV light, most of the colours glow very bright.

ちゃんと光る。スライムに入れたが、光に充てたりなど蓄光しなくても光って良い。

I mix this pigment with paint and make glow in the dark paintings with my kids. This pack is the perfect variety of colors and if you use just a little bit, it glows really well! It works so well that it even works with other items! (paints, gels, etc.) And it REALLY DOES make the resined items glow in the dark. You can swirl it in layers or make the whole thing glow with just a little bit of the powder. A little bit goes a long way, making your dollar go longer so it's definitely worth the price. I still have some and we must've used this in about 20 different projects. We recharge them with a UV light. It's pretty amazing.

Great product! Great glow. I was impressed and pleased with this product. Tip: when using some colours need a white base (e.g sky blue) This doesn’t prevent you from having a dark background just put white under where your gonna paint with the powder. It works wonders.

I used it in acrylic paint in a paint by numbers kit. It took some trial and error! I used a lot to get the glow I wanted and then the paint was powdery, so then I added a very small amount of acrylic paint flow medium, and it made the paint liquid again without diluting it! Here is a pic of the results when my painting is charged with a UV torch! It did brighten some of the colours due to the pigment in some of the powders, but I like it bright!
