This mug is simply called the "Coconut Tiki Mug" in the APS catalogue and on the U.K distributors website. It's designed and manufactured by APS Glass & Bar Supply in Germany. Rough matte brown glaze on the outside and glossy white in the interior. Marked "APS Tiki" on the base. 100mm high and with a diameter of 113mm... according to the website I got it off. In the UK you can only buy this design as a pair... but one of mine appears to have been lost in the post... GGGrrrrr!!!
