To use this magic mug, simply pour your favorite warm drink into it. You can use it for coffee, tea, or any other hot beverage. Since it's microwave - safe, you can easily reheat your drink in it. When it comes to cleaning, just pop it in the dishwasher. However, to keep its starry sky design and affirmation looking great for a long time, avoid using abrasive cleaners. If you wash it by hand, use a soft sponge. Also, be careful when handling it when it's hot to avoid burns.
