I think my biggest so far would be this but I'll have to wait to get that since shipping outside the US for that is super high and the only shops that have it available also sell the polish for like 25$. So I'll eventually get it when someone can bring it to me, where I live that would cost over 55$ in store.
Though this is awesome, I love the color and it costs like 10$ including shipping! Sadly their store doesn't really have a big selection and besides that they don't have anything I like and don't already have. Also lemming Zoya Storm because it's sooo pretty and I love glittery blacks. Plus I have all the scattered zoya holos besides this and Payton which I won't be getting because the color seems like it wouldn't look good on me at all.
