Mugs are super popular gifts for friends and loved ones. This mug changes color and will be the gift that keeps on giving. The heat-reactive surface reveals the design, Self Love, once the mug 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. Lead and BPA-free. Hand wash recommended.
