Pitbull Coffee Company Viking Tumblers
These 20-ounce tumblers will keep your coffee hot for hours; they'll also keep cold beverages cold. They feature double-wall insulation, copper lining, and a press-in, twist-closure lid with a vacuum seal. (Dog drool not included.)
Care instructions: Like many high quality tumblers, this one should be hand washed for the longest lifespan.
