Stanley Quencher H2.0 FlowState Tumblers are a type of insulated stainless steel drinking cup known for keeping beverages hot or cold for extended periods. They are made by the Stanley brand, a company founded in 1913.
The tumblers feature a comfort-grip handle, a narrow base designed to fit in most car cup holders, and a FlowStateTM lid with a rotating cover that has three positions: a straw opening, a drink opening, and a full-cover top to prevent spills. They are also often made with 90% recycled stainless steel.
The Stanley Quencher gained significant popularity through social media, with many users collecting them in various colors and posting about them online.
