To use this Harry Potter breakfast set, simply fill the mug with your favorite hot beverage like coffee or tea, and the bowl with cereal, oatmeal, or fruits. When it comes to cleaning, you can wash both the mug and the bowl in the dishwasher. However, to keep the color print on the mug and the design on the bowl looking great for a long time, avoid using abrasive sponges. Store the set in a dry place to prevent any damage. Enjoy your magical breakfast with this set!
