This was the first polish I tried for "black and/or blue week" on the forum. Turns out the following week was metallics, so this one would have fit right in there, too. Like the other Chanel polishes I've tried, the application and finish are flawless. It's WAY more interesting than I thought it was going to be when I picked it up on a whim because there are flashes of black, steel and even green in the sunlight. It has a pearly finish but the streaking is kept to a minimum.
