A thermal cup is a cup that keeps your beverages hot or cold for hours. It's made of ceramic, stainless steel, glass, or plastic and has a double-walled design that keeps your drinks fresh.
Insulated tumblers feature double-wall insulation, which keeps cold drinks cold and hot drinks hot. This means that not only will your drink taste better, but the mug itself will also be easier to carry. When filled with a hot beverage, the insulation protects your hand from feeling the heat.
