This vacuum flask has a compact design and is lightweight. It has a tight lid that fits perfectly and prevents any liquid from falling. It is leak-proof and is safe to be put in a travel bag. It can fit easily in most cup holders. It maintains the flavor and preserves the original freshness of the drink. Comes in beautiful white color with unique grey design to make it extra stylish! This thermos has double wall insulation with a vacuum inside. It prevents the heat from escaping out or entering in. This way it maintains a constant temperature inside and keeps the liquid hot or cold. This sleek and rugged sports water bottle is made from high quality food grade 18/8 (304) stainless steel that will not break. Even when filled with ice, the bottle will not sweat. No coaster needed! It is crafted and designed to last rust free. Better than using plastic or glass water bottles! Maintaining your stainless steel bottle is almost as easy as throwing a plastic bottle into the trash. Regularly rinse it with some warm soapy water and give it a good scrub with your bottle brush. Instructions: Fill the bottle with hot/cold water, attach the lid and let it rest inside for a few minutes. Empty the bottle and fill with your favorite beverage then attach the lid immediately. Fill the bottle to maximum capacity for optimum results. Wash and rinse thoroughly before first use and after each use. Use a soft sponge for cleaning the bottle.
