When the mug is cold, the mug shows a blackboard with apple; add a hot beverage and the mug shows objects familiar to teachers everywhere.
Wonder mugs are color-changing coffee mugs that change dramatically when a hot beverage is added.
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 microwavable. We recommend hand wash only to preserve the magic Wondermug ink.
