THIS is one of the best mugs seen in a long time.
Made of stainless steel it has all the features of a sturdy mug that can withstand extensive coffee drinking sessions.
Great ergonomic shape, easy to handle , this mug would qualify (I am sure) as a self defense tool in case of an assault on pacifistic coffee drinkers.
