As some of you know, I am obsessed with OPI nail polishes. In my opinion, they're one of the best polish companies around.
OPI launch about 4 different collections per year (if I'm not mistaken), and they also have celeb collaborations (like Katy Perry, Serena Williams, Minaj, Bieber etc.)
....and some time ago they also launched a new effect - liquid sand - which is a gritty, matte nail polish (which I have yet to try).
For Spring 2013, they're launching a new collection, this time in collaboration with Mariah Carey:
Which is yours? Would you try the liquid sand effect nail polishes?
