The new Gel II Cat Eye Reaction gel-polish is a magnetic, cat-eye effect polish that also changes color. To create the cat-eye effect, simply hold the included magnet over the wet polish for 3-5 seconds. The colors change based on body temperature, and for a quick transition, by placing hands in warm or cold water.
