Eco Cup Single-Wall Porcelain Mug with white or brown sleeve.

The Eco Cup is perfect for coffee or tea drinkers who want to cut down on wasteful disposable cups. Designed to look like the real thing, this sustainable mug provides all the benefits of a coffeehouse cup and lid, while replacing hundreds of throwaway cups.
Single-walled porcelain features a silicone sleeve that ensures you won't burn your fingers while holding the cup (never use the Eco Mug for hot beverages without the silicone sleeve). The high quality silicone lid fits securely, so you can drink on-the-go with no worries about spilling. Take this cup in the car, on the train or bus, or on foot, with your favorite local brew inside. Many coffeehouses are offering discounts for people who bring-their-own cup.
