I have my final Zoya Color of the Month from October - Viper. This is a midnight black base with tons and tons of holographic glitter.
I started with ella + mila Cover Your Bases ridge filling base coat, 2 coats of polish and finished with Zoya Glossy Seal top coat. This is a bit of a thirsty glitter, so you might want to add two coats of top coat.
This is a really nice black with glitter if you don't already own something like this. It's only on sale for today and tomorrow and then it goes away for good.
