Thermos flask MPM STT-25 420 ml — insulated travel bottle, stainless inner

MPM STT-25 is a 420 ml travel thermos engineered for maintaining beverage temperature during daily commutes and short trips. The flask has a compact, cylindrical shape for easy hand-held portability and fits in many cup holders. A screw-on lid doubles as a drinking cup, and vacuum insulation slows heat transfer to keep drinks hot or cold for extended periods. The stainless inner surface provides a neutral contact with liquids and is easy to clean.

Advantages

The vacuum-insulated construction reduces heat exchange and preserves beverage temperature without external condensation. The 420 ml capacity provides a balance between portability and volume for a full drink or multiple small servings. A screw cap that functions as a cup adds convenience when serving, while the stainless inner surface resists staining and interaction with flavours. The compact form factor is designed to be carried by hand or stored in a bag with minimal space impact.

How to use

Before first use, wash the thermos with warm soapy water and rinse thoroughly. To fill, unscrew the lid and pour the prepared beverage into the flask, leaving a small air gap at the top for pressure changes. Fasten the screw-on lid securely to maintain insulation and prevent leaks. Use the lid as a cup when serving. After use, clean the flask by hand with a bottle brush and mild detergent; allow to dry with the cap off.

Usage recommendations

For best temperature retention, preheat or precool the thermos by rinsing it with hot or cold water before filling. Avoid using abrasive cleaners or metal scouring pads on the stainless inner surface to preserve the finish. Do not place the thermos in a dishwasher unless manufacturer guidance specifies it is dishwasher-safe; hand washing helps maintain insulation performance and seals.
