How to use
Before first use, wash the flask, cap and mug with warm soapy water and rinse thoroughly. To fill, open the cap using the open-close button and pour the beverage into the main container; screw the cap closed securely to ensure the leakproof function. Use the removable 200 ml mug for serving; it can be rinsed or washed separately. Avoid filling with carbonated beverages or dry ice. For best temperature retention, preheat the flask with hot water or pre-cool it with cold water for several minutes before adding the desired drink.
Usage recommendations
Clean after each use and hand-wash the flask body and accessories; do not use abrasive cleaners or metal scouring pads. Do not place the flask in a microwave or on direct heat. Inspect seals periodically and replace if worn to maintain leakproof performance. Store with the cap removed to allow the interior to dry completely.
