## Long description

Maestro MR-1631-150 is a 1.5‑liter vacuum flask in green designed to keep beverages hot or cold for extended periods.

How to use
Before first use, wash the thermos and its components in warm soapy water and rinse thoroughly. Preheat the flask by filling it with hot water for a few minutes when storing hot beverages, or pre-chill it with cold water when storing chilled drinks; then empty and fill with the desired beverage. Close the screw cap tightly to ensure the airtight seal. Use the detachable 350 ml cup for pouring and serving. After use, disassemble the cap and rinse all parts; dry thoroughly before reassembly and storage.
Usage recommendations
To maintain optimal thermal performance and prolong the life of the thermos, avoid sudden temperature shocks (do not place the flask directly from freezer to boiling liquid). Clean regularly, avoid abrasive cleaners on the exterior finish, and hand wash plastic components. For safe transport, ensure the cap is fully tightened and position the thermos upright.
