Using this Harry Potter - themed Ravenclaw mug is easy. Just fill it with your favorite hot or cold beverage, like coffee, tea, or juice. When it comes to cleaning, you can wash it by hand with mild dish soap and warm water. Avoid using abrasive sponges as they might scratch the glazed finish. For storage, keep it in a safe place away from other heavy items to prevent it from getting chipped. Also, don't put it in the microwave or dishwasher as this could damage the mug's design and structure.
