Our first temperature-reactive, color changing nail polish. Watch as this heat-reactive polish magically transforms in hot and cold climates. Each mood-matching shade is fully pigmented with a matte finish. Degree in Hot is a Cornflower blue shade that turns to white. You're Hot Then You're Cold is a drak grey shade that turns to a pinky nude Directions for use: Apply one coat of base coat, followed by two coats of polish, finish with a top coat for glossy results. Watch the color change by warming nails up or running hands under hot or cold water.
