The beautiful finish makes this barware a stylish addition to your entertainment collection. The tumbler keeps its contents cold for hours, with vacuum insulation to beat the heat and prevent condensation from forming on the outside. It also includes a press-in lid with a silicone gasket that will protect your beverage from splashes during travel or toasting. With a capacity of 16 ounces, this stainless steel tumbler is completely BPA free and should be hand washed, though the lid is dishwasher safe. Do not microwave.
