This lining ensures your drinks taste exactly as they should, without that unwanted metallic hint that sometimes creeps in with metal cups. It’s a game-changer for coffee and tea lovers who want pure flavor, untainted by the vessel.

Boasting double-wall vacuum insulation, this tumbler promises to keep your iced drinks cold for up to 24 hours and hot drinks warm for as long as 6 hours.
