X-ray Scans Reveal Lead Pellet in Stanley Quencher, Pose No Health Risk

An industrial CT scan has confirmed the presence of a lead pellet in Stanley Quencher cups, which is safely sealed and inaccessible to consumers.

An industrial CT-scanning company, Lumafield, conducted X-ray scans of the Stanley Quencher, revealing a lead pellet used to seal the vacuum insulation at the cup's base.
The lead is entirely shielded by the cup's construction, making it inaccessible to consumers and posing no health risk under normal use.
Stanley has responded to concerns, stating that the lead is not present on any surface that comes into contact with the consumer or the contents of the product.
Alternative lead-free methods for sealing cups exist, but Stanley opts for lead due to its reliability in the manufacturing process.
Despite social media claims of lead contamination, Lumafield suggests false positives in home tests, lead in drinking water, or tampering with the cup as possible explanations.
