I was first introduced to Zoya nail polish in my Birchbox (see My Favorite Things: July 2011 post) where I received a sample size of the polish in the color Pandora. Zoya (Pandora) is a high quality polish that goes on opaque after one or two layers and has quite a bit of staying power. I did a quick polish on my nails and the color lasted with very little nail prep and no top coat for about a week. Impressive, for someone who washes their hands frequently!
My only qualm with the polish was that the color was not complimentary to my skintone. I have an olive complexion and the nude/pink shade of the polish made my hands look dead because they were so similar in color. Pandora would probably look best on lighter or darker complexions, but I highly recommend the brand.
Zoya nail polish can be purchased online, at Ulta, and other retailers. Remember to use your points and coupons when purchasing at Ulta!
