## Long description

The Maestro MR-1643-40B 0.4 L travel thermos is a vacuum-insulated stainless-steel flask designed to keep beverages hot or cold while on the move. With a 0.4-litre capacity and compact cylindrical shape, this grey travel thermos fits most car cup holders and standard backpack pockets. The screw-top lid provides a secure seal to reduce leaks and the stainless-steel construction offers corrosion resistance and straightforward cleaning. This model is intended for daily commuting, office use, and short trips where maintaining drink temperature is important.
Advantages
The vacuum insulation minimizes heat transfer, helping beverages retain their temperature for extended periods without external power. Its compact 0.4 L capacity balances portability and serving size, making it convenient for individual use. The screw-top closure and fitted spout reduce the risk of spills during transport, while the stainless-steel interior and exterior resist staining and odors. The neutral grey finish provides a discreet appearance suitable for professional and casual environments.

Daily commuting and travel between home and work

Key specifications
Capacity: 0.4 litres
Material: stainless steel vacuum-insulated body
Finish: grey
Closure type: screw-top lid with pour-friendly opening
Form factor: compact cylindrical flask designed for cup holders
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 for improved temperature retention. Fill the flask without overfilling, leaving a small air gap to allow for secure closing. Tighten the screw-top lid until it is snug to ensure the seal is effective. When pouring, open the lid according to the screw-top mechanism and pour slowly to avoid splashing. Clean the interior after each use with warm water and mild detergent; rinse thoroughly and allow to dry with the lid removed.
Usage recommendations
Do not use the thermos for carbonated drinks or dairy products intended for long-term storage. Avoid placing the flask in a microwave; handwashing is recommended to preserve insulation and finish. Inspect seals regularly and replace if damaged to maintain leak resistance.
