Viking Tumbler

Thanks to the double-wall insulation and copper lining, this tumbler is designed to maintain your beverage's temperature for several hours. While exact times vary based on the ambient temperature and how often you open the lid, it is built to keep drinks hot or icy throughout a standard workday.

The lid features a secure press-in, twist-closure design with a vacuum seal. While it is highly effective at preventing spills during normal use, it is always best to keep the tumbler upright when carrying it in a bag to ensure complete protection.

No, this tumbler should be hand washed only. Putting it in the dishwasher can damage the vacuum seal and the exterior finish, which will compromise the insulation performance over time.

The 20oz size is designed with a standard tapered base that fits comfortably in most vehicle cup holders. However, if you have an unusually small or non-standard cup holder, it is worth double-checking your vehicle's specific dimensions.

No, the double-wall insulation prevents heat transfer to the outside. You can hold a cup filled with piping hot coffee or ice-cold water without feeling the temperature on your hands, and you won't have to worry about condensation rings on your desk.
