The Rambler 10 oz. Lowball is the ideal drinking companion. Easy to stack and store, the Lowball's double-wall vacuum insulation will keep your hot drinks hot, and your cold rinks cold longer than standard drinkware. Enjoy your evening whiskey by the fire, and refill with coffee the next morning. Like the entire Rambler Drinkware Family, the Lowball and included MagSlider Lid are dishwasher safe for easy cleaning. While the magnet adds an additional barrier of protection to keep drinks contained and prevent heat or cold from escaping.
