Oooh I love this. And it's a freebie!
Moonlight Shadow is a super glossy green-with-a-big-dose-of-grey creme that was a Nails Inc cover mount giveaway with Marie Claire magazine back in April.
Although I'm a subscriber to Marie Claire (along with 10+ other magazines) several years ago Marie Claire changed the subscription model so you don't get any of the free gifts - gggrrgghh.
So I waited a few weeks and then started scouring eBay - sure enough the polishes started appearing - I think it must be from newsagents returns as they're usually available as a set of all 4 colours.
The four colours available were inspired from Moon-themed music.
I didn't have any issues with application and the swatches are 2 coats, no top coat.
