In today’s fast-paced world, vacuum flasks have become an essential companion for keeping beverages hot or cold for extended periods.

What is a Vacuum Flask?
A vacuum flask, also known as a thermos, is an insulated container designed to maintain the temperature of liquids. It works by creating a vacuum between the inner and outer walls, which minimizes heat transfer. As a result, hot liquids stay hot, and cold liquids remain cold for hours.
