Are you tired of diluting your drinks with melted ice? A vacuum insulated tumbler is the perfect solution--it keeps your drink cold for hours and as a bonus, prevents condensation from forming as well. This one also includes a press-in lid with a silicone gasket, which will protect your beverage from splashes during travel. The 13-ounce tumbler is made of stainless steel and completely BPA free. It should be washed by hand, though the lid is dishwasher safe. Do not microwave.
