Our 20oz CeCe brand tumbler is double wall 18/8 stainless steel with copper vacuum insulation, and it will keep your drinks cold for 24 hours or hot for 8. A clear push-on lid sits on top and a powder coated finish covers the outside. It comes in two looks, Navy w/White and White w/Navy. One care note: it is not dishwasher safe, so please hand wash. Fill it with sweet tea for the drive down 30A, or with coffee for the drive home.
