Thermos KOKO KO-6408 0.35 L — stainless travel vacuum flask, silver

KOKO KO-6408 is a 0.35 L stainless travel vacuum flask designed to keep hot or cold beverages at a stable temperature during daily commutes and short trips. The compact silver body and vacuum-insulated construction reduce heat transfer, while the screw cap offers a secure closure suited for carrying in bags. The 0.35-litre capacity fits single-serve use for coffee, tea or cold drinks and balances portability with thermal performance.

Advantages

The stainless steel inner and outer walls with vacuum insulation provide prolonged temperature retention without adding excessive weight. The compact 0.35 L size makes the flask easy to carry and store in backpacks, briefcases or cup holders. A screw cap ensures a tight seal to prevent spills during transport, and the silver finish is scratch-resistant and simple to clean.

How to use

Preheat the flask by filling it briefly with hot water, then empty before adding your hot beverage to improve temperature retention; for cold drinks, pre-chill the flask similarly. Secure the screw cap tightly before carrying to avoid leaks. Clean the flask after each use with warm water and mild detergent; avoid abrasive cleaners and submerging the cap if it contains non-stainless components. Allow the flask to dry thoroughly with the cap removed before storing.

Usage recommendations

Do not use the flask in a microwave. Avoid dropping or subjecting the flask to strong impacts to preserve the vacuum insulation. For best thermal performance, fill the flask close to its rated capacity and limit opening the cap frequently.
