Using your personalized coffee mug is a breeze. Just fill it with your favorite hot or cold beverage and enjoy. When it comes to cleaning, you can either hand - wash it gently or use the dishwasher as it's dishwasher - safe. In the microwave, it's also safe to use for reheating your drink. As for maintenance, try to avoid dropping it or hitting it against hard surfaces as it's made of ceramic and can break. Keep it in a safe place when not in use.
