SANDJEST Viking Tumbler

Thanks to the double-wall vacuum insulation, this tumbler is designed to maintain your beverage's temperature for several hours. While performance varies based on the starting temperature and ambient conditions, it is well-suited for keeping coffee hot during a morning commute or water cold throughout the workday.

The included lid is designed for convenient sipping and splash resistance, making it ideal for travel and office use. However, it is not fully leak-proof, so it is best to keep the tumbler upright rather than tossing it loosely into a bag.

While the stainless steel construction is durable, we recommend hand-washing the tumbler to preserve the integrity of the Norse-inspired design and the vacuum seal over time. Harsh dishwasher detergents and high heat can degrade the finish.

Yes, the 20-ounce capacity is designed with a tapered base that fits comfortably into most standard vehicle cup holders, making it a practical choice for daily commuting.

Yes, the included straw is made from durable materials intended for repeated use. We recommend using a straw brush to ensure it stays clean and hygienic between uses.
