THERMOS King Insulated Flask 0.5 Liter Matte Black

The THERMOS King Insulated Flask 0.5 L Matte Black SK-500BKM is a vacuum container for carrying hot or cold drinks on short trips, commutes, and walks. It holds 0.5 L — enough for a moderate serving during daily use. A screw stopper seals the opening to prevent spills while on the move. The exterior has a matte black finish for a neutral look in everyday settings. This design suits both indoor use and daily outings when a moderate amount of liquid is needed close at hand.

The outer housing is built to resist dents and impacts during transport. Measuring 70 mm in diameter and 250 mm tall, the flask has a slim cylindrical profile. This shape fits easily into standard bag pockets and cup holders. Weighing 360 g when empty, it is portable enough to be carried with other gear without adding significant bulk. The bottle has no integrated carrying handle, relying entirely on its compact form for handling. A single internal chamber holds the beverage, with no dividers inside.
