CRACKED OUT

Nail trendsetters like Katy Perry and Serena Williams may have been the muses behind OPI's latest offering, but trust us, this new kind of nail art doesn't involve hand-painted flowers or delicate polka dots.

Instead, this is a graffiti-inspired topcoat that thrives on imperfection. All you have to do is apply Black Shatter over any nail color, then watch as the dark layer literally forms cracks so that the base shade peeks through.

What's amazing is that each nail makes a different pattern that's impossible to predict, but really fun to watch. We tried it over a lilac hue, but we think it would be even cooler layered on top of neon or metallic shades.

So go ahead, experiment- and don't be afraid to get a little messy.

Available in January.
