Durable 18 ounce thermal insulated coffee mug with lid. Designed to last a lifetime, these mugs are made using two layers of high grade polycarbonate (the same product used to make prescriptive eyeglass lenses). It's double walled construction is like putting one mug inside another. The air trapped between the two walls keeps your cold drinks really cold and your hot drinks hot for longer. The mug has a clear plastic snap on lid with a sipper spout. Choose from blue with white symbol or white with blue symbol.
