One is the top lid designed to be conical, which can make the droplets formed by condensed water vapor return into the mug due to gravity; the other is the mug body is made of two-double insulating glass, the surface of the glass is covered a layer of aluminum, on which surface a dense layer of oxide film will also be formed, this oxide film can prevent the layer of aluminum from continuous reacting with oxygen and water. On the other side, this layer of aluminum can react with oxygen under high temperature and emit a lot of heat, which can help to repeatedly heat the water inside the mug and increase the insulation time.
