This stainless travel-size tumbler is vacuum-insulated and built to last. It's perfect for showing off your style on the road, at the office, or in the country-side. Any drink that is hot, like coffee, can stay hot for up to 6 hours. Cooler drinks, (i.e. lemonade), can stay cold for up to 24 hours. The high-quality stainless steel tumbler and the double-walled insulation design ensures beverage can stay either hot or cold over time.
