There is concern that the popular "Stanley" drinking cups contain lead.
According to the company, "yes" lead is used in the manufacturing process, but the cup would have to be damaged in order to expose the lead.
"There is a circular barrier made of stainless steel on the bottom of the cup that covers a pellet which contains lead," according to a Stanley spokesperson.
The pellet seals the product's vacuum insulation, and it is not accessible unless the stainless-steel barrier is breached.
The Stanley spokesperson says the lead exposure is "possible but rare.”
