How to use

Preheat the thermos by filling it with hot water for a few minutes before adding a hot beverage, or pre-chill it with cold water for cold drinks.

To pour, open the cap and tilt the flask slowly to control the flow.

Usage recommendations

For best thermal performance, avoid frequent opening and closing; fill the flask with liquid at the desired serving temperature and minimize air space inside by filling close to the neck. Clean the thermos regularly with warm soapy water and rinse thoroughly; avoid abrasive cleaners and do not place in the dishwasher to preserve insulation and exterior finish.
