How to use

Preheat or precool the thermos by filling it with hot or cold water for a few minutes, then empty before adding the beverage to improve temperature retention. Fill the bottle without exceeding the recommended capacity, secure the lid tightly, and transport upright to minimize the chance of leakage. Clean the interior after each use with warm soapy water and allow to air dry with the lid removed. Do not place the thermos in a microwave; follow any additional manufacturer care instructions for cleaning and maintenance.

Recommendations

For best thermal performance, pre-warm with hot water when carrying hot drinks or pre-chill with cold water when carrying cold drinks. Avoid filling with carbonated beverages as pressure build-up can occur. Inspect the lid seal regularly and replace if damaged to maintain leak protection.
