Our tumbler 20 or 30 oz. 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 drink slider 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 and other colors.

Mary Beth –
I love my ion cup. I take it everywhere. Keeps my water cool for hours. I don’t leave home without it.
