Zoya FeiFei is a very cool-toned, dark blue with a frost finish. It is a permanent nail lacquer that retails for $9.00 and contains 0.5 oz.
Zoya FeiFei Nail Lacquer ($8.00 for 0.50 fl. oz.) is described as a "medium steel blue base with heavy gold, blue, and pink iridescent metallic sparkle." It's a cool-toned, purpled blue with a hint of steely gray skies, then coated with blue, green, and dark pink sparkle. I don't have anything quite like it. Zoya Skylar has one or two similarities, but it is largely different. China Glaze Skyscraper is a similar blue, but the base color is darker, and it has mostly silver sparkle.
