You've seen it everywhere.  From Katy Perry to Beyonce..nail art is IN! Your local drugstores are now carrying nail art pens and fabulous pre-designed press on lacquers are showing up at Sephora, so how can you get these expensive looks without money for the salon or a steady hand? EASY:

O.P.I. Shatter Collection
