Using your personalized coffee mug is easy. Just pour your favorite hot or cold beverage into it. When it's time to clean, you can safely put it in the dishwasher. For heating your drink, it can be used in the microwave. However, avoid dropping the mug as it's made of ceramic and may break. To keep it looking great, don't use abrasive cleaners. This mug is proudly printed in the USA with copyrighted artwork, so handle it with care to maintain its unique design.
