Sally Hansen recently updated their collections and the Diamond Strength bottle design. The new colors are lovely but the only one I have picked up so far is Black Tie. Black Tie is an awesome black duochrome that shines blue, purple, green, and pink. The duochrome is obviously more visible in the bottle than on the nail. Despite that the color is still pretty awesome!
I couldn't get a decent picture of the color changing magic to save my life. But boy did wearing it convince others to buy the polish at work! Sally Hansen Diamond Strength retails for $4.99 at Walgreens.
