Just wanted to show you this fierce nail polish.
It's from Barry M, but you can get similar ones from other brands as well. You can choose whatever base color you prefer, and I happened to have the Rimmel #239 Your Majesty on already so that's my base color. It's pretty amazing to watch the nail polish as it transforms from just a matte black coat
to the next step when you suddenly start to see the base color appear through the cracks as they evolve.
(I would advise you to apply a top coat afterwards because it's quite fragile)
You can see a short tutorial here on the Barry M page.
Cool isn't it?
