Butter London The Black Knight. Multicolored glitters in a black jelly base.
I layered it over Finger Paints Black Expressionism so I didn't have to worry about doing too many coats for opacity (it would probably require three coats if you were wanting to wear it by itself).
I was underwhelmed by this polish. It just didn't seem to sparkle when I wore it. The glitter seemed very flat.
I used two coats of top coat over it and it was nice and smooth, so that was a plus. I'm going to give it one more try before I decide whether or not to keep it in my stash. I've got BL Tart with a Hart and I plan on layering the two polishes together next time.
