Zoya Ultra glitters are some of the best polishes I have ever used. The best thing about them is that they are super easy to touch up. If you get a chip you can just dab a little on and put top coat over it and it looks as good as new.
Asta is the reddish one. In my picture you can't really tell a whole lot of difference between Astra and Nova, but in real life Astra is reddish and Nova is purplish.
As I said I love these because of their fixability factor and the fact that it's so glittery it's saving a step of putting a glitter over regular polish. Love it!
