## Summary description

Maestro MR-1643-40A is a 0.4 L vacuum insulated thermos designed to keep beverages hot or cold. Constructed as a portable flask with leak-resistant lid and compact size, it suits travel, work, outdoor activities and daily use. The green finish identifies the model visually; capacity and insulation properties make it suitable for single-person servings and short trips.

## Long description

Maestro MR-1643-40A is a 0.4 L vacuum insulated flask designed to maintain beverage temperature for hours. The double-wall stainless steel construction with vacuum insulation and a cool-touch exterior keeps hot drinks warm up to 12 hours and cold drinks chilled up to 24 hours. The compact 0.4 litre capacity, leakproof cap with an open-close button and odour-proof lid make this green casual-style thermos suitable for single-person servings, commute, and short trips.
Advantages
The flask combines a stainless steel inner vessel with a rubber-coated housing that provides a secure, non-slip grip and a cool outer surface. A double-wall vacuum design minimises heat transfer while the overflow protection and odour-resistant lid improve hygiene and usability. Lightweight at 290 g and 235 mm tall with a 6 cm diameter, the thermos is easy to carry and fits most cup holders. Its leakproof closure and keep-warm function allow stable temperature retention without spills.
Suitable for
Hot beverages on the go (coffee, tea)
Cold drinks for outdoor activities
Daily commute, work or study breaks
Short hikes and travel where single-serving capacity is enough

How to use
Before first use, wash all detachable parts with warm soapy water and rinse thoroughly. To fill, open the cap using the open-close button, pour the desired beverage and secure the cap until it clicks to ensure a leakproof seal. For best thermal performance preheat with hot water or precool with cold water for a few minutes before filling. Do not use the thermos in a microwave. Clean the flask by hand; avoid abrasive cleaners to preserve the rubber housing and stainless steel finish.
Usage recommendations
Use the keep-warm function for beverages you plan to consume within 12 hours and the cold retention for up to 24 hours. Tighten the closure after each refill to maintain leakproof performance and store the thermos with the lid removed when not in use to avoid odour buildup.
