## Long description

Maestro Thermos MR-1641-45 insulated flask 0.45 L, Blue is a compact vacuum-insulated bottle designed to maintain beverage temperature for single-serving use. With a 0.45 litre capacity and a slim profile, the flask is intended for everyday carry, travel, office use and short outdoor activities. The screw-top lid provides a secure closure to reduce spills, and the lightweight construction makes it convenient to pack in a bag or backpack.
Advantages
The vacuum-insulated construction reduces heat transfer, helping to keep drinks hot or cold for extended periods compared with non-insulated containers. Its 0.45 L capacity is suitable for individual portions without adding bulk, while the slim cylindrical shape fits most cup holders and small compartments. The screw-top lid ensures a tight seal, and the durable exterior resists dents and scratches typical of daily use.
Suitable for
Carrying coffee, tea or other hot beverages during commuting
Keeping water or cold drinks chilled during short hikes
Office desk use for single servings
Travel and daily errands where a compact thermos is needed
Key specifications

How to use
Preheat or precool the flask by filling it with hot or cold water for a few minutes, then empty before adding the beverage to improve thermal retention. Screw the lid on firmly after filling to ensure a secure seal. To pour, unscrew the lid and tilt the flask; replace the lid immediately after use to retain temperature. Clean the flask regularly according to care instructions to maintain performance.
Usage recommendations
Do not use in microwave ovens. Hand-wash the flask with warm soapy water and allow it to air dry with the lid removed. Avoid dropping the flask or subjecting it to strong impacts to preserve the vacuum insulation. For best results with hot beverages, preheat the flask with hot water; for cold drinks, pre-chill it with cold water or ice.
