To use this mug, simply fill it with your favorite hot or cold beverage. It's suitable for both coffee and tea. When it comes to cleaning, you can wash it in the dishwasher or by hand. Just use mild dish soap and warm water. Avoid using abrasive sponges as they might scratch the glazed finish. For long - term use, store it in a dry place away from direct sunlight and sharp objects. This will keep the mug looking great and the Konoha Ninjas images vivid for a long time.
