Why Vremi Travel Thermos Mug and Tea Thermos Large Bottle are not on the list

Vremi thermoses remain popular in the market for their purpose of keeping hot and cold beverages at their preferred temperature.

Vermi Tea Therm Large Bottle is also often criticized for its inability to keep the beverage hot for longer time periods and tends to cause leakage.

For how long can I keep my tea in a thermos?
