Read previewThe news that Stanley's insulated stainless steel cups contain lead sparked a frenzy of concern on social media about the potential health risks for consumers. Stanley acknowledged in a statement that it uses "an industry standard pellet" that contains "some lead" to seal the vacuum insulation of its tumblers. We want to assure you that Hydro Flask does not use lead in our vacuum sealing process," HydroFlask said in a post on Threads earlier this week. Marketing experts told Business Insider this is a smart strategic move for companies seeking to differentiate themselves from Stanley and win over customers. And lead is still bad for manufacturing workers and the environment — it's just not a significant health risk for Stanley customers.
