Alright lets get started, The Katy Perry Collection by OPI will include four shades and a crackling topcoat: Teenage Dream (a pink glittery color), Not Like the Movies (a silver color), Last Friday Night (a glittery purplish blue), The One That Got Away (a berry color), and Black Shatter (crackling topcoat creates a cracked-like pattern). Its a very easy to apply and i notice that with every stroke that i apply on the same nail, it will look more sparkling. Bought this at Metro and it cost me $21. I'm including the how to do video for the Black Shatter effect. Hope you enjoy it.
