Vacuum Excellent Office Cup - Silver

Description

A vacuum office cup is a type of insulated cup designed to keep drinks at a desired temperature for extended periods of time. It works by using a double-wall vacuum insulation technology, where the space between the inner and outer walls of the cup is vacuum-sealed to prevent heat transfer. This means that hot drinks such as coffee or tea can stay hot for several hours, and cold drinks like water or juice can remain cold for even longer.
