Thermoses

1892. That’s how long the “vacuum flask” has been around. It’s an amazing invention with a double-walled container inside of it. The air between the two walls is sucked out during construction, creating a vacuum.

Heat can be transferred through the air. To keep heat from escaping, you need insulation. The best insulator possible is a vacuum.

A variety of thermoses are out there and we can get our hands on many of them then put them in your hands with branding to fit your cause.
