ETS Spark Tumbler

The Spark Tumbler features copper vacuum insulation and double-wall construction, which is designed to maintain beverage temperatures for several hours. While performance varies based on ambient temperature and how often the lid is opened, it is highly effective for standard daily commutes and office use.

The clear push-on lid includes a swivel closure, which helps prevent splashes and minor spills while you are walking or at your desk. However, it is not designed to be 100% leak-proof, so we recommend keeping the tumbler upright in a bag.

18/8 stainless steel is a food-grade material that is highly resistant to rust and corrosion. It also does not retain flavors or odors from previous drinks, ensuring your water or coffee tastes fresh every time.

To preserve the integrity of the powder-coated finish and the vacuum seal, we recommend hand washing this tumbler. Harsh dishwasher detergents and high heat can degrade the exterior coating over time.

With a 12 oz capacity, this tumbler has a compact profile that fits comfortably in most standard vehicle cup holders. Its sleek design makes it a convenient choice for travel.
