From TikiLand Trading Company:

"King Coconut, while beach combing the sands of the seven seas, found the perfect vessel for his favorite libations.

From that point forward, King Coconut carried his half coconut with him, filled with his favorite tiki concoction, toasting to any crustacean along the way.

His thirst for adventure was only matched by his thirst to fill his empty coconut!

This mug holds about 17oz (varies slightly mug to mug), and is about 5.5 inches tall.

Designed and Sculpted by TikiLand Trading Co., in sunny Southern California. Imported."

There is also a second edition blue version of this design.
