Is Stanley Lead Safe?

If you're wondering is Stanley lead safe, the short answer is no. A lead pellet is used to seal the insulation in Stanley's vacuum-insulated tumblers during production. Each quencher has a stainless steel barrier at the bottom that protects the pellet from the liquid within by keeping lead out of direct contact with it. A representative for Stanley claims that there is very little chance of lead exposure and that it only happens in the "rare" event that the stainless steel cover falls off and reveals the lead pellet.
