This is interesting coconut mug that has a unique design that sadly only permits it being used in conjunction with a straw. The interior is white while the exterior is rough with a unique brownish-green glaze. Three indented spots appear to be realistic coconut features. The bottom of the mug is imprinted with the words "Made Exclusively for the Akua Kai". There are no other unique features except that it feels real good to hold it. Cool mug.
