It couldn't be more fitting that Katy Perry, one of THE masters of the nail art game, chose to work with OPI for a collection of glittery, shimmery, and crackle polishes. The nail colors were named after all of her songs ("Last Friday Night," "The One That Got Away") and featured a black crackle top coat that (at the time) was REVOLUTIONARY. She was a pioneer of bringing crackle polish the forefront of finger fashion, and for that, we salute her. (The next OPI collaborator Nicki Minaj ALSO added crackle in her line as well. That makes TWO cosigns on crackle.)
