This mug is called the "Caribbean" in the APS catalogue and simply "Bamboo" on the U.K distributors website. It's designed by Dirk Rehder and manufactured by APS Tiki (there's a thread about them on the Tiki Central forums). All over dark blue/black glaze. This one is unmarked on the base. 15cm high and 8cm wide... according to the website I got it off.
