Is My Stanley Cup Giving Me Lead Poisoning?

The Stanley FlowState H2.O Quencher Tumbler

Stanley 1913

An insulated water bottle has become the next purse. It’s a fashion statement started by TikTok nurses and “clean girls” who had to make water a trend…and while there are several brands trending like Hydroflask and Owala, one prevails: the Stanley.


The Stanley FlowState H2.O Quencher Tumbler is highly sought-after – their Valentine’s Day drop caused lines to form outside Targets around the country at 3 AM. You’ve seen Stanley cup accessories like snack holders…but have you heard about your Stanley tumbler having lead in it?

Not a week goes by where I don’t see some sort of shocking Stanley lore on the internet, whether it be two grown men fighting over the last cup or now people getting lead poisoning from their Stanleys. But it has everyone asking the same questions, so let’s answer them!

Do Stanley Cups Have Lead In Them?

The short answer is yes. Stanley uses lead in its manufacturing process through a pellet at the bottom of the cup. It’s sealed, so you never should be fine if your Stanley has not been cracked. If you test your Stanley tumbler right now, it will probably come up negative for any sort of lead…so you’re safe!

However, if you take the bottom cover off and the lead pellet cracks, you may be at risk to ingesting lead. If you think this has happened to you, you can submit a claim through Stanley’s lifetime warranty policy.

In fact, Tamara Rubin aka ” Lead Safe Mama“, has dedicated her site to keeping children safe from lead. Using XRF technology to test the presence of lead in items, Lead Safe Mama has been sent many Stanley tumblers that she says have detected positive for lead…but the company released a statement saying it’s extremely rare,

“Once sealed, this area is covered with a durable stainless steel layer, making it inaccessible to consumers. Rest assured that no lead is present on the surface of any Stanley product that comes into contact with the consumer nor the contents of the product,”

If the whole situation spooks you and you want to rid yourself of your Stanley, I understand and empathize. In fact, so does Hydro Flask, who made sure to point out they don’t use lead in their sealing process at all…multiple times…across multiple social media platforms.

It’s fun to see the girls fighting like this…but it’s safe to say your water bottle is probably fine!
