Just when I thought mood rings were long gone, Kiss Nails releases an updated variety of color-changing innovations. This time, what changes is the color of your press-on nails, and it's not according to your "mood" (read: body heat), it's according to the sunlight. From the apparition of stars, polka-dots and pretty tones on your finger tips, you'll never know what's coming.

I wonder if the Kiss Nails press-ons ever change to black. Perhaps in a rain storm?
