Black Swirl is a metallic black with a silver pearl shot through it, It almost looks like a gunmetal grey in some lights. When it catches the light though, it really comes to life and you can clearly see the silver metallic sheen to it. I love it, it's so much more glam than a flat black.
It took two coats to get the bottle colour, and it dried nice and fast. I didn't use a topcoat, and it lasted on my nails for a couple of days before chipping .. (I really must invest in a topcoat..)
Here is how it looks :)
It is so pretty isn't it? .. I will have a NOTD soon with the other shade so look out for that.
