Using your personalized coffee mug is super easy. Just fill it with your favorite hot or cold beverage and enjoy. When it's time to clean, you can simply pop it in the dishwasher as it's dishwasher - safe. If you want to heat up your drink in the microwave, that's okay too because it's microwave - safe. To keep it looking its best, try not to use abrasive cleaners as they might scratch the ceramic. Also, handle it with care to avoid any accidental drops that could break it. This mug is printed in the USA with copyrighted artwork, so enjoy showing off its unique design.
