To use the water bottle, first ensure it is clean by washing it with warm soapy water. To fill, unscrew the lid and pour your favorite beverage into the bottle, making sure not to exceed the maximum capacity. Close the lid securely. For easy drinking, press the one-touch button to open the spout with one hand. After use, rinse the bottle and lid thoroughly to maintain hygiene. The stainless steel material allows for easy cleaning; simply wash it by hand or place it in the dishwasher. Enjoy your drink while keeping it hot or cold for up to 6 hours!
