I love this polish. It's so cool. It's a black glitter! In the photos it looks like there are blue pieces but that is just the black reflecting the light - it's all black glitter. It's not going to be to everyone's taste but this is a pretty sweet polish. I can see this being really great to franken with to create other black based glitter polishes.
This is one coat over Orly Mirror Mirror. It looks like fabric or lace over the nail.
