Is There Actually Lead in Stanley Cup Tumblers? Yes and No

These days it's hard to escape the phenomenon that is the Stanley Tumbler.

The insulated drink containers have become the country's go-to product and even reached elite pop culture status with a Saturday Night Live skit mocking its very existence.

But with that incredible popularity comes the inevitable backlash.

Recently, a number of Facebook posts and TikTok videos have been posting results of in-home tests that appear to show the tumblers testing positive for the presence of lead.

So are these tests legit or are they the latest batch of misinformation being shopped around on the internet?

As it turns out, there IS lead in the Stanley Tumblers, but the company has an explanation.

Best Life is reporting that Stanley released a statement to WCNC-TV in Charlotte, confirming that its cups are manufactured with a part that includes lead:

'We seal our vacuum insulated stainless steel products with an industry-standard pellet that includes some lead. There is no lead present on the surface of any Stanley product that would come into contact with the user or the liquid inside. The pellet is completely enclosed by a stainless-steel cover, making it inaccessible to consumers.'

According to U.S. Food and Drug Administration, lead is toxic to humans of any age, and is most dangerous for children, as high levels can cause learning disabilities, behavior difficulties, and lowered IQ.

If it makes you feel any better, Stanley does says that in the 'rare' case that a base cap comes off a tumbler, that product is eligible for a replacement through its Lifetime Warranty.
