Double Wall Glass

Double walled glasses is basically glass within glass. The air between the two glasses is sucked out, creating a vacuum. Instead of using heating or cooling elements to keep your drink hot or cold, it keeps your drink at the correct temperature by not allowing heat to escape or enter. Double-walled glasses keep your drinks the right temperature from the first sip to the last. July Household keeps offering best double walled glasses at low costs for bulk buyers.
