The perfect coffee mug has arrived! Our new Black Dog 12ounce Ceramic Lined Mug features all the benefits of an insulated mug— but without the metallic taste of stainless steel to interfere with your coffee's perfect flavor. Smooth, ceramic coating preserves the taste of your drink, while the vacuum-insulated stainless steel exterior keeps beverages hot all day long. The leak-proof, pop-open lid is easy to use, and fits snugly into the ceramic lining. And at 12oz, it fits comfortably into any standard cupholder so you can enjoy your commute just a little bit more!
