## Summary description

Maestro MR-1631-100-BLUE is a 1-liter thermos flask designed for tea and coffee.

## Long description

Maestro MR-1631-100-BLUE is a 1-liter thermos flask designed to keep tea, coffee and other beverages at the desired temperature during daily use, travel or outdoor activities. The insulated vacuum construction minimizes heat transfer, while the screw-top lid provides a secure closure for spill-resistant transport. The compact cylindrical design and 1 L capacity make it suitable for sharing or prolonged single-person use.
Advantages
The vacuum insulation maintains beverage temperature for extended periods, reducing the need for reheating or chilling. A screw-top lid helps prevent leaks and retains heat better than simple press caps. The 1-liter capacity balances portability and volume, enabling multiple servings without excessive weight. The simple construction is easy to clean and maintain.
Suitable for
 Keeping hot coffee or tea warm during work shifts or meetings
 Carrying cold drinks for day trips, hiking or picnics
 Use at home to avoid repeated reheating of beverages
 Shared use during small group outings where several cups are needed
When it may not be suitable
This thermos is not intended for use with carbonated beverages, as pressure build-up may occur when sealed. It is also not a travel mug designed for single-hand drinking while walking; the screw-top lid requires unscrewing for pouring. If ultra-compact or very lightweight options are needed, a smaller-capacity or non-insulated bottle may be preferable.
Key specifications
 Capacity: 1 liter
 Function: insulated vacuum beverage container for hot and cold liquids
 Closure: screw-top lid for secure sealing
 Intended use: tea, coffee and other non-carbonated beverages
 Design: cylindrical, portable for daily or outdoor use
How to use
Preheat or precool the thermos by filling it with hot or cold water for a few minutes before adding the desired beverage to improve temperature retention. Fill to an appropriate level, close the screw-top lid tightly to minimize heat transfer, and place the flask upright during transport. To pour, unscrew the lid and pour into a cup or directly from the flask if the opening allows controlled pouring. Clean by hand washing the interior with warm soapy water and allow to air dry completely before storage.
What to consider before purchase
 Required capacity — 1 L may be large for solo commuters but suitable for sharing.
 Type of beverages — avoid sealing carbonated drinks in a vacuum flask.
 Portability — screw-top provides secure sealing but is less convenient for one-handed sipping.
 Care — designed for hand washing; confirm if any parts are dishwasher-safe before using a dishwasher.
Usage recommendations
For best performance, pre-warm or pre-chill the thermos before filling, close the lid tightly, and store upright. Regularly clean the interior to avoid flavor transfer between beverages.
