believe me, don't believe me... eitherway, I'm the Mistletoe Tester.
Or you are, depends on who is holding the cup.
These 20 oz. tumblers are stainless steel, great for keeping your cold beverages icy and your coffee piping hot for hours! They feature double wall insulation, copper lining and a press-in, twist-closure lid with a vacuum seal. A drink tumbler that is high quality but won't empty your wallet!
