One coat of yellow for base and one coat of blue Depend Cracked Effect Polish.
I liked the Cracked Effect polish, although it started cracking really fast. I wasn't even finished with the one side of the nail, when the other already cracked. That can be a good thing if you get it all perfect on the first try, but if not.. Well, then it may come out like my second picture's index finger.
Overall, it's a great polish and really affordable - the 5 ml bottle was 1,50 € since it was a campaign price, but the regular price can't be that much higher.
