Using your personalized coffee mug is easy. Just fill it with your favorite hot or cold beverage and enjoy. When it's time to clean, you can safely put it in the dishwasher. You can also heat up your drink in the microwave without worry. As for maintenance, since it's made of high - quality ceramic, it should last a long time. But be careful not to drop it, as ceramic can break. If you have any issues, feel free to contact us at
