Serco Group plc ordered the insulation cup as winter gifts. The tumbler is made of sturdy and environmentally friendly materials, and its durability is praised. Thermos vacuum insulation technology virtually eliminates temperature change within the beverage container by creating an airless space between two stainless steel walls. A superior insulated container you can depend on to keep your beverages, colder, hotter, fresher, longer. It is a great choice for long days out and about or in the office with this stainless steel vacuum thermos mug.
