"Stanley Insulated Steel Tumblers: Company Acknowledges Presence of Lead in Products"

Stanley PMI confirms that their popular insulated steel tumblers contain a sealing material with "some lead," but assures consumers that the lead does not touch any surface of the product or come into contact with beverages. The company states that the lead is inaccessible to consumers and that the products meet all US regulatory requirements, including California’s Proposition 65. They are also working on alternative materials for the sealing process. Despite the surge in popularity, consumers are advised to clean the tumblers regularly and handle them with care to preserve their finish.
