Stanley Quencher 40oz Tumbler

The Stanley Quencher 40oz Tumbler is a vacuum-insulated drinkware product designed to keep beverages cold for extended periods. Introduced in 2016, it gained significant popularity through social media platforms, particularly TikTok, where it became a viral sensation. The tumbler features a 40-ounce capacity, double-wall vacuum insulation, and a versatile FlowState™ 3-position lid with three sip settings: one for the reusable straw, one without, and the option to rotate the silicone cover shut. It is primarily manufactured in China, with some production also occurring in Brazil. The Stanley brand was established in 1915 by the Stanley Insulating Company in the United States. In 2002, the brand was acquired by Pacific Market International (PMI), a subsidiary of The HAVI Group LP, a global company specializing in supply chain management and logistics services. As of 2026, PMI continues to own and operate the Stanley brand, with no known local subsidiaries or distributors.
