Founded in 1946, family owned and operated, Florida?based Tervis? designs and manufactures insulated drinkware and accessories; the insulated tumblers use a double?wall technology to harness the natural insulating properties of air. The insulation reduces condensation and keeps beverages hotter or colder longer than non?insulated cups and glasses; today, as they have been from the beginning, each tumbler is made in America. The drinkware is available in a variety of sizes and configurations including tumblers, mugs, goblets, collectible cups and water bottles plus the company offers accessories such as handles, travel lids, straw lids and straws. The microwave, freezer and dishwasher?safe beverage containers and tumblers fit in most cup holders and are designed to keep hot beverages warm and cold beverages cool. The company has an in?house design team and also features the logos of major sports and entertainment brands on the timeless drinkware.
