How to use

Before first use, rinse the flask with warm water. To use, preheat or precool the bottle by filling it briefly with hot or cold water, then emptying and adding your beverage. Secure the screw-top lid firmly to minimize heat loss and prevent leaks. Avoid overfilling; leave some headspace to allow the lid to close properly. Hand wash the interior with mild detergent and a soft bottle brush; rinse thoroughly and allow to air dry. Do not use abrasive cleaners or metal scouring pads on the exterior finish.

Usage recommendations

For optimal temperature retention, pre-warm the thermos with hot water for several minutes before adding hot beverages, or pre-chill with cold water before adding cold drinks. Avoid placing carbonated beverages in the sealed flask to reduce pressure build-up. Store with the lid off when not in use to prevent odors.
