Color-changing Nail polish!!! I'm in love. It really changes color in sunlight! And once you walk back indoors, it changes back to the original color. Awesome. I think I'm in love now.. This shade (peek-a-boo) is perfect if can't or don't like wearing bright colors or must wear nude/neutral colors to work. Doesn't change in artificial lighting-- only sun light! Perfect for summer.
buy it here! The company also has a plethora of other products that changes in the sunlight. So cool. Check them out :)
