Using your personalized coffee mug is easy. Just pour your favorite hot or cold beverage into it and enjoy. When it's time to clean, you can safely put it in the dishwasher. It can also go in the microwave to reheat your drink. However, be careful when taking it out of the microwave as it can get hot. To keep your mug in good condition, avoid using abrasive cleaners that might scratch the surface. Also, try not to drop it as it's made of ceramic and could break. This mug was printed in the USA with copyrighted artwork, so enjoy this unique piece every day.
