24oz Midnight Botanical Tumbler with Straw

• Features Therma-S’well® Technology with triple-layered, vacuum-insulated construction designed to keep beverages colder or hotter, longer than all the rest. • The 24oz Tumbler with Straw keeps drinks cold for 18 hours and hot for 5. • Made from 18/8, food-grade stainless steel to reduce the need for single-use cups. • Offers a condensation-free exterior that won't sweat in your hand or on your table. • BPA/BPS-free and reusable. • Top-rack dishwasher safe. Although dishwasher safe, S'well recommends hand washing with warm soapy water and air drying with the lid removed to extend the life of your product, as use of a dishwasher may cause the finish to fade.
