Turn your everyday disposable cup into a reusable mug. DCI’s double-walled, thermal porcelain cup is ideal for commuting, sporting events, and the office. The flexible silicone lid helps keep beverages hot or cold for longer and helps prevent messy spills. The two layers of porcelain, which are separated by a hollow cavity, act as a perfect insulator for hot and cold beverages and ensure that you won’t burn your fingers. A silicone stopper in the cup’s base prevents water from entering the hollow cavity when washing the mug. This porcelain cup is both microwave- and dishwasher-safe, holds approximately 12 ounces, and measures 3-1/2 by six inches.
