Keep drinks cold for up to 24 hours or hot for up to 8 hours with the triple-layer insulating stainless steel construction of the Tervis® 20oz Triple-Walled Insulated Tumbler in "Best Mom Ever" Yellow Floral! Sandwiched between the tumbler’s 18/8 stainless steel exteriors is a copper lining similar to that used in quality cookware. Those layers help maintain the temperature of any drink whether hot or cold and reduce condensation on the tumbler’s exterior. The easy-close slider lid seals tightly to prevent leaks and is made from BPA-free clear plastic. Printed directly on the stainless surface with eco-friendly plant-based inks, this tumbler is a really great idea to gift your mom on Mother's Day. To best preserve and maintain the tumbler’s artwork, hand wash with soap and a scratch-free sponge. Do not soak or put in the dishwasher, freezer, or microwave. Help mom stay hydrated in the great outdoors in style with her very own Tervis® 20oz Triple-Walled Insulated Stainless Steel Tumbler with Lid!
