The popular Stanley cup brand, owned by Pacific Market International, is facing a class action lawsuit following allegations of undisclosed use of lead in its products. The company recently announced the launch of its new "Chroma Quenchers and Classic Bottles" line via social media. Since 2020, Stanley has sold approximately 10 million of its Quenchers, contributing to an annual revenue of about $70 million before experiencing a significant increase in 2020, with a reported revenue of $750 million for 2023.

However, amidst the excitement of new merchandise releases and high-profile collaborations, a lawsuit was filed claiming that a Stanley tumbler purchased for $35 from Target in March 2023 contained lead, a highly toxic metal. The plaintiff in the lawsuit stated that the presence of lead made the product essentially worthless, as it posed a safety risk to her and her family, a concern exacerbated by the fact that the company did not disclose the use of lead in its products at the time of purchase.

Despite the allegations, Stanley's website features a "FAQ" section where the company transparently addresses the use of lead in its products and assures customers of their safety. Pacific Market International has not released an official statement regarding the lawsuit as of yet. The lawsuit highlights the importance of transparency in product manufacturing and raises questions about consumer trust and safety standards within the industry.
