Volvo Word Mark is etched on the front of the Blue Yeti Rambler 20 oz. Tumbler with MagSlider™ Lid. The Rambler is made from durable stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs. 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. The Tumbler and its lid are dishwasher safe for easy cleaning.
