Released with Serena Williams and Katy Perry's OPI nai lpolish line, Black Shatter cracks upon drying giving your nails a bit of a punk-rock edge. To achieve this shattered look, application is easy. Just apply a coat of Black Shatter on top of the color of your choice (I chose a simple nude color) and wait until it dries. For just $8 a bottle, I am loving this look! If you are lucky enough to come across this nail polish, grab it!
