At Stanley, one of the key features of our products is our vacuum insulation technology, which provides consumers with drinkware that keeps beverages at the ideal temperature. The vacuum insulation in our products has been sealed using an industry standard process that includes pellets, some of which include some lead, and all of which are covered with a durable stainless-steel layer, making them inaccessible to consumers.


All Stanley products are safe. Rest assured that no lead is present on the surface of any Stanley product that comes into contact with the consumer nor the contents of the product. 


If the base cap comes off during ordinary use, the product may be eligible for our Lifetime Warranty, available here:


Stanley ensures that its products meet all US regulatory requirements, including CA Proposition 65. Stanley tests for and validates compliance on all products through FDA-accredited 3rd party labs that verify our products follow strict guidelines, including BPA/BPS, PFOS, and phthalate regulatory requirements, among others.
