These tumblers, made of durable stainless steel with double-wall vacuum insulation, are ready to protect your hot or cold beverage on your daily rounds. These tumblers are designed for maximum ice retention, with no sweating on the outside. The magnet on the MagSlider lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, but please note - this magnet component is not leakproof and will not prevent spills.
