The Ardesto AR2645WC thermal mug from the Coffee Time Meowning series is designed to keep your favorite drinks at the right temperature while you are on the move. With a capacity of 450 ml, it features a double-wall construction made entirely of stainless steel, which ensures that hot beverages stay warm for up to 8 hours and cold drinks remain chilled for up to 16 hours. This beige mug is equipped with a convenient button-valve opening mechanism for easy one-handed use. Its slim dimensions of 20.5 x 8.1 cm make it easy to fit into most car cup holders or bags, while the BPA-free materials ensure your drink stays safe. Because of its construction, you should wash it by hand rather than using a dishwasher to maintain its thermal properties.
