These mugs are so cute and fun! They are a bit small, about the size of an apple and hold about 1 cup of liquid instead of the standard 2 cup coffee mug. Fully functional, the ceramic will insulate your beverages (hot or cold) and maintain the temperature for quite a while. They're the perfect size for a nice hot cup of green tea. They are dishwasher safe and there is a clear glaze coating over the entirety of the mug so the face will not rub off in the wash. Easy to stack and fun to hang on display. Guaranteed to put a smile on your face!
