You are probably referring to the California Proposition 65 Warning, which reads as follows:
WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
The State of California requires this warning on all products that include any chemicals from a list of over 860, including nickel. It is important to note that this warning is not required in any of the other 49 states nor does it appear on Lifetime Products shipped internationally, as it is not required in other countries either. It is printed on all Lifetime Products in the U.S.; because of how our shipping distribution works, the destination is determined at distribution and not packaging, so all products carry the Prop 65 warning in case they go to California, even though the warning is not required in any other state.
Lifetime Products are made with high-quality steel. Nickel is a naturally occurring metal and the fifth-most common element on earth. It is a component in almost all steel in the entire world, including the coins used in U.S. currency. There is no evidence that nickel nor any other material used in any Lifetime Product causes cancer or any other kind of harm to the human body. We would never sell a harmful product to any customer. The California Proposition 65 Warning is a legally required message that is included only as a precaution on almost all products sold in the state of California.
