The product that changed the drinkware industry forever was created by two Detroit engineers in 1946 who figured out how to harness the natural insulating properties of air. The product was purchased by a Florida entrepreneurial family in the 1960s. With a love of the outdoors, it was easy for them to market this double-walled drinkware that would keep beverages hot or cold for hours. Though modern printing is offered on all Tervis products, you can still get the nostalgic embroidered emblems with your logo set between the tumbler walls.
