In 1986, California enacted the Safe Drinking Water and Toxic Enforcement Act, commonly known as Proposition 65. The Act requires businesses to notify California consumers about specific chemicals in their products that are known to cause cancer and birth defects or other reproductive harm, usually by way of a product warning label. The presence of these chemicals does not necessarily mean that the products are harmful, but the labeling requirement allows consumers to make informed choices about exposure.


All Cliff Weil, Inc. products containing such chemicals in quantities above safe harbor levels, as determined and published by the State of California, will carry a Proposition 65 warning label. To date, California is the only state with this requirement. For more information about this law, visit the official website.


The following Proposition 65 warning applies to any product linked to this page:

⚠️ WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer, and Bisphenol A (BPA), which is known to the State of California to cause birth defects or other reproductive harm. For more information go to
