The "Eco Cup" Porcelain Cup looks just like an average paper cup -- but it's anything but. Made of smooth white porcelain, this ecologically friendly coffee cup includes an attachable lid, which helps keep beverages hot or cold for longer. The lid can withstand temperatures over 400 degrees Fahrenheit, and helps prevent messy spills. The "Eco Cup" also comes with a silicone sleeve, which slides around the cup and prevents burns. Just like at your favorite coffee shop, the sleeve lets you pick up your extra hot beverage safely and comfortably. Measuring 95mm in diameter and 135mm tall, this porcelain coffee cup holds 16 oz. of your favorite drink, and prevents excessive waste of paper cups to better protect our environment. Microwave and dishwasher safe for convenience.
