Using your personalized coffee mug is easy. Just fill it up with your favorite hot or cold beverage. It's safe to use in the dishwasher, so cleaning is a breeze. When using in the microwave, make sure there are no metal parts or decorations that could cause issues. For long - term use, avoid dropping or hitting the mug against hard surfaces as the ceramic might crack. Keep it in a dry place when not in use. That's all you need to know to enjoy your special coffee mug.
