Stanley Cups Contain Lead, Pose Risk Only if Damaged

Lead poisoning activist Tamara Rubin first highlighted the issue, prompting Stanley to explore alternative materials for sealing process.

Stanley, a beverage container manufacturer, uses lead in the manufacturing process of its cups, but the lead is not accessible unless the stainless steel barrier at the bottom of the cup comes off, which is rare.
Stanley is working on alternative materials for use in the sealing process and all its products follow U.S. regulatory requirements.
Lead poisoning activist Tamara Rubin first brought attention to the presence of lead in Stanley tumblers in March 2023.
Lead is a naturally occurring metal that can cause severe health consequences, including cardiovascular disease and brain damage, if it enters the bloodstream.
Stanley is not the only company using lead-containing pellets to seal its insulated cups, this is an industry standard.
