The mug is about 5 inches tall and approximately 17-18oz capacity. There might be slight differences in shape and dessince it is hand-thrown on a pottery wheel and individually hand-illustrated. I leave the exterior unglazed for a raw, stone-like touch and a better feel, but the handle and inside is glazed. This object has the artist's touch and imperfections of a natural raw surface clay that uniquely differentiate it from factory made ceramics. It is food safe, dishwasher and microwave friendly.
