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.

Care instructions: Like many high quality tumblers, this one should be hand washed for the longest lifespan.  Just like your favorite cat — don't put it in the dishwasher. ;)
