Tervis Traveler Tumbler

Yes, it is. The exterior features DuraPrint technology, which is designed to withstand the dishwasher without chipping, peeling, or fading over time.

The base diameter is 2.8 inches, which is designed to fit most standard cup holders. However, because the top diameter is 4.1 inches, it is best to measure your specific vehicle's cup holder if it has a restricted opening.

No, the copper-lined interior is specifically designed to prevent metallic aftertastes and lingering odors. It ensures your beverage tastes exactly as it should, whether you are switching between coffee, tea, or water.

While exact times vary based on ambient temperature and how often you open the lid, the triple-insulated construction is engineered to maintain your beverage's ideal temperature for several hours.

The slider lid is designed for convenience and splash resistance during daily use, such as commuting or walking. It is not intended to be 100% leak-proof, so it is best to keep the tumbler upright rather than tossing it into a bag.

The base is designed to provide stability on smooth surfaces and reduce noise when you set the tumbler down. It prevents the cup from sliding around on your desk or countertop and eliminates that loud 'clanking' sound common with all-metal tumblers.
