A vacuum-insulated stainless steel tumbler will keep any drink the perfect temperature. The tumbler holds 20 ounces and is made to last through everyday wear and tear. The insulation keeps hot drinks hot and cold drinks cold for hours, as well as preventing condensation from forming. It has a lid that will eliminate splashes and spills when you're on the go, and the stainless steel and plastic materials are completely BPA free. The tumbler should be hand washed, though the lid is dishwasher safe. Do not microwave.
