Sephora by OPI nail polish. It's $9, which is a lot for a polish, but there are so many great colors to choose from. It's irresistible! It stays on well...and did I mention the color range? So extensive, and the glittery colors are to die for. There are several glitter top coats, too, that look great on top of color or just on a bare nail. I also like the Nail Treatment-Brightener (it really did make my nails look whiter) and the polish remover is great. Hurray OPI and Sephora!
