So I decided that I'm going to post some of my old nail polish looks to I can catch up and have everything up.
Pink- Orly's Oh Cabana Boy (Two coats)
Black- O.P.I.'s Black Shatter (One coat)
I noticed it's best to do a thick coat rather than a thin coat. You get bigger black chunks and more interesting cracks. You also want to make sure not to layer the black. Make sure to only use one coat!
That was my first experimentation of Black Shatter. Nice look, right?
