This polish was released as part of China Glaze's Anniversary Collection. It was a series of 10 polishes, all named a roman numeral from I to X. After looking through the pics of all the colors, this one is the only one that stuck out to me.
China Glaze X
Formula and application were good. I believe I'm wearing two coats here. X is a dark burgundy/brown with multi-color shimmer. The color isn't terribly unique, but it's nice, dark and vampy, which is nice. Another winner for China Glaze!
