Let me start by saying these paints are GORGEOUS when they catch the light. I used them to jazz up some handmade greeting cards, and the metallic shimmer had my friends asking 'Where'd you get that?!' The 40-color range means you can go from ocean blues to sunset oranges without missing a beat.
But here's the tea - these palettes are TINY. Like, 'I almost lost them in my art drawer' tiny. Each is barely larger than a credit card, which was super disappointing when I first opened the package. However, the colors are surprisingly pigmented - a little goes a long way if you're patient with water ratios.
The shifting effect works best on dark paper in my experience. I tried them on watercolor paper first and got more of a subtle sheen than the dramatic glitter effect shown in ads. But when I switched to black cardstock? Magic. Suddenly those metallics popped like fireworks.
Biggest surprise? They work amazingly for nail art! After testing on paper, I painted my thumbnail with the teal shade (mixed with just a drop of water) and got compliments for days. Dries crazy fast too - no smudging when I accidentally brushed against it minutes later.
Would I recommend? For $15-20, it's decent if you manage expectations. Not professional grade by any means, but fantastic for craft projects where you want that extra sparkle. Just don't expect large pans or intense glitter payoff from one swipe.
