OPI Black Shatter over Nicole My Lifesaver. Washed out (and my skin looks weirdly red) because of the flash, but this is really more about the Shatter than the base color. Look how perfectly it crackled! I love this stuff so much. It's so much better than the old crackle polishes. It crackles so quickly and doesn't take an hour to remove. I also think it's quite funny that I'm wearing a Katy Perry nail polish over a Justin Bieber nail polish. Two musicians that I know next to nothing about and would rather eat my mother-in-law's turkey lasagna than listen to even one their songs.... Yet here they are on my nails, their colors joined together in perfect harmony and greatly admired by me.
But, yeah, I really love this combination. Nice contrast between light base color and black crackle effect.
