This is Maximillian Strass-her from Essie, Spring 2013 Collection. I almost passed this one over, I have a gray that I thought was similar. I ended up buying it anyway because I am an addict. I can't help it. But, I'm glad it did because it looks much prettier on my nails than in the bottle. It is not a plain gray at all, it has strong green undertones. Greens and blues look great on me, so that's probably the reason I like it so much. The formula was amazing! Not runny at all, just thick enough and practically a one-coater!
