Here is the polish I'm wearing right now, TiNS The Summer Night Rules.
I used three coats. It's a dark gray jelly filled with tiny silver glitter.
It reminds me a little of OPI My Private Jet, although I realize there are distinct differences.
The brush was just a bit wonky, but nothing major.
I think I originally expected this one to be a true black, but it's definitely gray.
I still haven't taken the time to swatch wheels with the rest of my TiNS! :(
Hopefully I can get it done soon.
