Description Hot air balloonists prepares for a dawn launch as the sun cracks the horizon. When the mug changes, witness the favorite sight of balloon enthusiast: the mass ascension. Wondermugs are color-changing coffee mugs that change dramatically when a hot beverage is added. If you’re looking for a unique gift, what a way to remind them of you daily! These unique, high quality gift mugs utilize color-changing or “thermochromatic” ink that changes color when hot beverages are poured into the inside of the mug. Color change gift mugs are ideal for fund raisers, birthday gifts, teacher’s gifts, corporate gifts and more. All mugs are microwaveable. We recommend hand wash only to preserve the magic Wondermug ink.
