The Etna 10 oz Stainless Steel Tumbler is a great product for those who love outdoor activities such as hiking and camping, or need a high quality tumbler for their morning commute. It is made by an industry leading manufacturer who produces drinkware for brands like Starbucks, Target, and Costco. We now use premium 3D laser engraving for the best possible imprint. It allows us to make huge imprints that wrap around the curvature of the bottle without warping. The premium powder coating on the exterior keeps it more durable and more presentable as it won't collect fingerprints like bottles with gloss finishes. * Made from 18/8 304 lightweight, lead Free stainless steel which won’t alter flavors or leach chemicals. Durable quality, rust-proof and unbreakable.
