I think my (now) MIL actually bought this one for me! It's long discontinued, like the rest of Cover Girl's NailSlicks line, but it can probably still be found on eBay or in dollar stores. Midnight Metal is a shimmery gunmetal grey -- seems pretty basic but I haven't seen a proper dupe yet. This is a true grey: no bluish, greenish or reddish tones. I never found Cover Girl NailSlicks to be very good quality, but this one actually still applies quite well. Maybe I got a good bottle, or this colour was just one of the winners from the NailSlicks line. Definitely pick this up if you ever stumble across it for a good price!
