William Stanley Jr. forever changed the way drinks were kept hot with his 1913 invention that combined the strength of steel with vacuum insulation. In the Master Series, Stanley ups the ante with 1-mm thick 18/8 stainless steel for the ultimate in rugged durability and maximum insulation. This stainless steel alloy traps no flavors, so your beverage will always taste like it should.
