NARS "Mash" was re-released last year with NARS "Vintage Nail Polish collection". It's named after the 1970 war comedy & TV series with the same name (both are based on the novel "Mash: A Novel about 3 Army Doctors"). You can read about them here.
"Mash" is an army green with gold shimmer. It's bordering on being metallic, but it's surprisingly unstreaky. (The macro shot makes it look streakier than it actually is.)
The formula is a little bit thick, but applied well, though. It took 2 coats for opacity & dried very quickly.
