Trick or Treat Color Morphing Mug 11oz

Trick or Treat! Enjoy hot cocoa or some spiced cider as you hand out goodies on Halloween night. The mug's heat-reactive surface reveals stars, typography and a cute little bat as it gets warm. The ceramic cup will go back to its original black outside and white inside when it cools down. The C-shaped handle helps keep a sturdy grip. It comes in one size – 11oz (0.33l) – plenty for that big morning cup of coffee. Hand wash only, please!
