Are Stanley Cups Lead-Free?

Stanley's official comments say that under typical use circumstances, there is no risk to customers from this design element since the lead pellet stays out of touch with the liquid within the cup.

Are Stanley Cups Causing Lead Poisoning?

There is no evidence to suggest that Stanley cups cause lead poisoning when used as intended. The risk of lead exposure arises only if the cup is damaged in such a way that the lead pellet becomes exposed. In such instances, Stanley advises consumers to cease using the product and take advantage of the company's lifetime warranty for a replacement and stop using the compromised cup immediately.

Navigating Concerns and Ensuring Safety

Recent social media posts and advocacy by influencers such as Tamara Rubin, also known as Lead Safe Mama, have highlighted the potential risks associated with lead in consumer products especially drinkware. While these concerns are valid, Stanley claims their approach to product safety and compliance with regulatory standards in the USA should serve as reassurance to consumers about the lead-safe status of their cups and bottles.
