The Hidden Dangers of The Stanley Cup

The cup that has taken the world by storm and dominated the internet is now under scrutiny for potentially containing lead. Chances are you’ve heard of the viral sensation known as the Stanley Cup and you’re either a big fan or are confused by its widespread appeal. While its rise to fame began in 2019, the brand has been around since the early 1900s. The Quencher, Stanley’s newest stainless steel tumbler, is loved for its large size, robust build, and ability to keep drinks cold for extended hours. The revamped design has gained popularity amongst a large female audience and is available in sizes ranging from 14 to 64 fluid ounces. It conveniently fits in car cup holders, outperforming competitors like Hydro Flask and Yeti. Its integrated straw is another great feature, enabling continuous hydration without having to physically open the lid. According to Forbes magazine, the cups' popular 40-fluid-ounce size raised Stanley’s annual sales from $75 million to $750 million in 2023. 

However, the cup was found to have a flaw the company had failed to mention. According to a recent USA Today article, several lawsuits have been filed against the brand following customers’ discovery of lead through at-home testing. The test results sparked widespread outrage among customers, caused by the brand’s failure to warn about potential lead exposure. As news spread across social media, Stanley was forced to address the growing questions and concerns surrounding the cup. They revealed that the sealing material used inside contained some lead but reassured customers that there are no reputable cases of lead in the inner portion that holds the water. There have also been no reports of the cup causing any health issues. Stanley calls the claims made about their tumbler to be meritless. 

Before panicking about your own Stanley cup, it’s important to understand that there’s no cause for concern unless the base cap of the product becomes detached, exposing the seal. For those wondering what the base cap looks like, you can find it at the cup’s bottom in a small circular barrier with the company logo. Experts emphasize that this area is inaccessible to those drinking from the cup and mention that at home lead tests can be unreliable. A Stanley spokesperson also added to this point saying that the possibility of the base cap coming off is rare. Owners of the Stanley can continue to use their cups as they remain safe for use until further notice.
