Using your personalized coffee mug is easy. Just fill it up with your favorite hot or cold beverage. You can safely put it in the dishwasher for cleaning, and it can also be used in the microwave. However, when using the microwave, be careful as the mug might get hot. For long - term use, avoid dropping the mug as it's made of ceramic and could break. And that's it, enjoy your custom coffee mug every day!
