The Tully 30oz 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 double walled and vacuum sealed design prevent heat and cold transference to the outer walls of the tumbler, so it's always comfortable to hold, and keeps hot drinks hot and cold drinks cold. 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. The Tully is made from high quality 18/8 304 food grade stainless steel. Lead free and durable. Rust-proof, easy wash, dishwasher safe and unbreakable. It's also BPA Free so you are safe from toxins, and the Electro-polished interior doesn't affect flavor or leave a metal aftertaste. Designed for car cup holders.
