Double-walled vacuum flask WAS 1.5 L — 14 cm diameter, 22 cm height

WAS double-walled vacuum flask, 1.5 L capacity with a 14 cm diameter and 22 cm height, is designed to maintain beverage temperature while reducing external heat transfer. The vacuum insulation between two walls helps keep hot drinks hot and cold drinks cold for extended periods. The flask's size and form factor make it suitable for tabletop serving, portable transport, and everyday use in domestic or professional environments.

Advantages

The double-walled vacuum construction provides reliable thermal retention and reduces condensation on the exterior surface. A 1.5 litre capacity accommodates multiple servings without frequent refilling. The compact 14 cm diameter and 22 cm height balance volume and portability, allowing the flask to fit on counters or in carry bags. The design minimizes spills and supports straightforward pouring and serving.
