Using your personalized pet face coffee mug is easy. Just pour your favorite hot or cold beverage into it. You can use it in the microwave to heat up your drink or pop it in the dishwasher for a hassle - free clean. When using in the microwave, be careful as the mug may get hot. Avoid dropping or hitting the mug on hard surfaces as it's made of ceramic and can break. To keep it looking great, don't use abrasive cleaners. Just a mild dish soap and a soft sponge will do the trick.
