Maestro MR-1631-100 1 L is a vacuum-insulated travel thermos designed to maintain beverage temperature during transport. Constructed from stainless steel with a vacuum layer between walls, this travel bottle secures liquids with a screw-top lid and offers a 1-litre capacity suitable for single-person use throughout a workday, commute or outdoor activity.

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. Pour liquids carefully to the maximum safe fill level, screw the lid on tightly and carry the bottle upright to avoid spills. To drink, unscrew the lid and pour into a cup or drink directly if the lid design allows. Allow the thermos to cool to room temperature before cleaning.

Usage recommendations

For optimal thermal performance, avoid overfilling and do not place carbonated or highly acidic beverages for prolonged storage. Hand wash the thermos with warm soapy water and a soft brush; avoid abrasive cleaners and dishwashers to preserve the finish and insulation. Inspect the lid seal periodically and replace if worn to maintain leak resistance.
