How it works; you take the darker coat and paint it on your nails. Then you just paint the sparkle side over it!
I was a bit skeptical because the sparkles looked really flashy and I wasn't too sure about the colour. But once it's actually on the nails, it blends in with the darker colour and takes on this really neat, almost tie dye-like form. The only down side to this polish? It's expensive and the sparkles get used up REALLY fast; I've only used it twice and the sparkle side is half empty. But what can ya do.
Here's what it looked like on my nails. This is called Revlon's "Nail Art Moon Candy" in "Galactic"!
