Thermos Maestro MR-1631-150, vacuum flask 1.5 L, green

Maestro MR-1631-150 is a 1.5‑liter vacuum flask in green designed to keep beverages hot or cold for extended periods. The stainless steel insulated body with a vacuum seal reduces heat transfer and preserves temperature: up to 12 hours for hot drinks and up to 24 hours for cold. The thermos includes a screw cap that ensures an airtight closure, an ergonomic grip for comfortable handling and a removable cup with a 350 ml capacity for convenient serving while travelling, at the office or during outdoor activities.

Advantages

Its airtight screw cap and sturdy plastic components prevent leaks and make the thermos suitable for transportation.

Design features include an ergonomic grip and smooth interior surfaces that simplify cleaning.

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.
