Insulated Travel Mug- Check out our gorgeous Frost Tumbler, a full 20 oz double wall vacuum insulated tumbler. That means a large beverage you can take on the go that will stay cold and frosty or piping hot for hours. The interior is 18/8 stainless steel. Why does that matter? If you want your drink to taste fresh and pure, not like whatever you last used your tumbler for, then 18/8 stainless steel is the way to go. And no need to worry about sloshes or spills, thanks to the clear acrylic push-on swivel lid. With your custom logo and the gift box included with each Frost Tumbler this is the perfectly packaged and ready to give promotional gift for your clients and employees.
