Key specifications
Capacity: 1.5 L
Insulation type: vacuum-insulated
Material: high-quality stainless steel (interior and exterior)
Closure: screw-top
Thermal performance: up to 24 hours heat retention for hot liquids under typical conditions
Design: ergonomic for easier pouring and handling
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. Fill to an appropriate level, secure the screw-top closure tightly to minimize heat transfer and prevent leakage, and keep the flask upright during transport. 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.
