Using this Mr Boo ghost - shaped mug is super easy. Just pour your favorite hot or cold drink into it. For hot drinks, be careful as the mug might get warm. After each use, wash it with mild dish soap and warm water. Don't put it in the dishwasher to keep the bow tie's color and the mug's shape in good condition. Dry it with a soft cloth and store it in a safe place, away from other heavy items that could damage it.
