Using this mug is a breeze. You can fill it with any beverage you like, such as coffee, tea, water, or beer. Just pour your drink in and enjoy. When it comes to cleaning, it's dishwasher - safe, but you can also use a mild detergent and a sponge to clean it by hand. As for the microwave, it's safe to use, so you can reheat your drink without worry. Keep in mind that although it's made of high - quality ceramic, handle it with care to avoid dropping it, as it could break. Also, don't use abrasive cleaners as they might damage the 3D inflated effect print. With proper care, this mug will serve you well for a long time.
