Let me start by saying, these glow powders are FUN. I used them in resin art and slime, and the glow effect is seriously impressive. After just 30 minutes under a lamp, my projects lit up like mini neon signs in the dark. The glow lasts for hours, and the intensity is way better than other brands I've tried.
The color variety is great during daytime - vibrant pinks, blues, greens that look gorgeous in resin. But here's the catch... many colors don't glow as advertised. That pretty pink? Glows orange. The red? Also glows orange. You basically end up with about 4 actual glow colors instead of the promised 12.
Texture-wise, some colors clump more than others (looking at you, blue shades). I had to really work to break up lumps when mixing with resin. The gold foil flakes are a nice bonus though - they add beautiful metallic accents to projects.
Would I recommend? Yes for the glow power, no if you need specific glow colors. They're fantastic for general glowing effects but don't expect the exact hues shown in product photos.
