A person opening a sleek black tumbler.

A person is demonstrating a black insulated tumbler with a silver rim. They open the lid, pour champagne into it from a green bottle, and then close the lid. The video highlights features like 'BevGuardTM Tech', 'Keeps Your Drink Ice-Cold With No Metallic Taste', 'Glass-Free Zone Friendly', 'Holds 12 oz', 'Twice As Much As A Normal Champagne Flute', 'Flip-Top Lid Holds In Carbonation', 'Twist Off For Easy Cleaning', and '20x Colder Than A Normal Champagne Flute'. The setting appears to be a bar or home with wooden surfaces and shelves in the background.
