Using this Lilo & Stitch gift set is easy. You can use the mug to enjoy your daily coffee, tea or any other beverage. The coaster is there to protect your table from spills and heat marks. Just place it under the mug when you set it down. The keyring can be attached to your keys, backpack or purse for a fun touch. When it comes to cleaning, wash the mug and coaster with mild dish soap and warm water. For the keyring, a simple wipe with a damp cloth will do. Avoid using abrasive cleaners as they might damage the print on the mug and the keyring. Store the set in a dry place when not in use to keep it in good condition.
