Like the entire Rambler Family, the 887 ml Tumbler and whichever lid you put on it are dishwasher-safe for easy cleaning. While the magnet on the included MagSlider Lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, please note - this magnet component is not leakproof and will not prevent spills. Available in Stainless, Duracoat colours and seasonal finishes.
