20 OZ TUMBLERS ~ Comes with clear slider lid, and a plastic straw. Keeps drinks hot or cold for up to 4 hours. Made from double-walled non-toxic stainless steel. ***Some dishwashers use high heat/dry cycles which may cause the ink to reactivate and cause some running. They should be hand washed only*** (as well any double walled tumbler should be hand washed to preserve the seal) Many of the images shown are mock ups only to show available design options. End results may vary slightly as colours display differently on different screens.
