Stainless steel, double-wall vacuum-insulated tumblers with an airtight seal that retains heat and cold, to keep your drinks ice cold longer and warm beverages piping hot. The outside stays dry with its sweat-proof exterior. All three tumblers have brand new, unused secure lids that prevent spills. The narrow and tall design fits more cup holders. The pink 20 oz coffee tumbler has a small ding on the bottom, but remains steady and balanced when placed on a flat surface. It was also used for coffee, and still has a slight coffee stain but it’s been soaked in hot soapy vinegar water and scrubbed with a steel wool pad…there is absolutely no lingering coffee smell.
