Botella isotérmica Feel-Maestro MR-1641 0,45 L azul

The Feel-Maestro MR-1641 vacuum flask holds 0.45 L and is finished in a blue stainless steel housing. It is designed to maintain beverage temperature for extended periods while remaining lightweight and compact enough to fit in bags and most vehicle cup holders. The flask includes a screw-top lid that helps prevent spills and a narrow body profile for easy carrying during travel, commuting, or outdoor use.

Advantages

Thermal vacuum insulation reduces heat transfer, helping to keep hot drinks warm and cold drinks chilled for hours. The 0.45 L capacity balances portability with sufficient volume for single-person use, and the slim shape improves compatibility with backpacks and cup holders.

How to use

Preheat or precool the flask by filling it briefly with hot or cold water, then emptying before adding your beverage to improve temperature retention. Unscrew the lid to fill or pour; secure the lid tightly after use to maintain insulation and prevent leakage. Clean the interior after each use with warm water and mild detergent, rinse thoroughly and allow to air dry with the lid removed.

Recommendations

If using hot liquids, handle the flask carefully and test the lid seal before placing it in a bag. Avoid using carbonated or perishable liquids for long-term storage. Do not place the flask in a microwave. For best results, clean regularly and avoid abrasive cleaners that could damage the finish.
