Stainless Steel Flask Mug 400ml – Keeps Drinks Hot or Cold Longer

Enjoy Long-Lasting Temperature Control with Our Stainless Steel Flask

A stainless steel flask is essential for anyone who wants to keep beverages hot or cold for extended hours. Our flasks are designed using stainless steel with a double-walled construction. The vacuum between the walls effectively prevents heat transfer, allowing liquids to maintain their temperature for 12 to 24 hours. Whether you’re traveling, hiking, working in the office, or simply using it at home, this flask is a reliable companion for daily hydration needs.

Key Features of Stainless Steel Flask

The stainless steel flask includes a silvered inner surface to reduce heat loss by radiation. Additionally, a tightly sealed cap minimizes heat loss through convection, keeping your drinks at the right temperature. These flasks are BPA-free, durable, and easy to clean, making them a practical choice for daily use. For the best performance, avoid using them with carbonated drinks, acidic beverages, or hot milk, as these may affect the flask’s longevity.
