How to use

Preheat or precool the flask by filling it briefly with hot or cold water, then empty before adding your meal to improve temperature retention. Fill the container without overfilling, close the screw lid tightly and transport upright when possible. For hot contents allow a short stand time before serving to avoid scalding. Clean the wide-mouth opening and interior after each use according to care instructions to maintain performance and hygiene.

Usage recommendations

For best thermal performance, avoid filling the flask only partially; filling nearer to the top reduces internal air volume and improves heat or cold retention. Hand wash the interior with mild detergent and a soft brush; avoid abrasive cleaners and prolonged soaking that may affect seals. Do not place the flask in a microwave. Check the lid seal regularly and replace if damaged to maintain leak resistance and insulation efficiency.
