Using this mug is easy! Just fill it up with your favorite hot drink, like coffee or tea. Since it has a 440ml capacity, it can hold a good amount for your morning pick - me - up. When it comes to cleaning, don't put it in the dishwasher or the microwave. Instead, wash it by hand with mild dish soap and warm water. This will keep the mug in good condition and preserve its cute ghost and pumpkin design for many Halloweens to come.
