To use your Thermos vacuum insulated tumbler, fill it with your chosen beverage, being careful not to overfill, then close the lid firmly until it clicks into the locked position. To drink, release the lock by sliding or pressing the mechanism and enjoy through the opening. After each use, wash the tumbler thoroughly. For optimal temperature retention, pre-condition the tumbler by filling it with hot or ice-cold water for a few minutes before adding your drink.

Clean the tumbler by hand using warm soapy water and a gentle cloth or sponge. Avoid abrasive scrubbers or steel wool, which may scratch the surface. Do not microwave or place in the dishwasher. Let all components dry fully before reassembling and storing. Avoid impacts and extreme temperature exposure to keep the vacuum seal intact.
