Stanley Flip Straw Tumbler

The Stanley brand was founded in 1913 by William Stanley Jr. in the United States, following his invention of the all-steel vacuum bottle. This revolutionary design replaced the fragile glass linings used in traditional vacuum flasks, making the products favorites among outdoor enthusiasts and workers alike. Over the decades, Stanley products became synonymous with durability and thermal performance.

Today, the brand is owned by PMI Worldwide (Pacific Market International). Following an acquisition in 2022, PMI became part of HAVI Group, a global supply chain and logistics giant. While the brand maintains its American heritage and engineering roots in Seattle, Washington, the majority of its manufacturing operations are now located in China to serve its massive global demand, particularly for the popular 'Quencher' and 'Flip Straw' series.
