California Prop 65 Information:

What does the Prop 65 Warning on my product mean?

“This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm,” may not be what you expect to see when you receive a new item. You may even find it alarming. However, if you live in the state of California, you will find this warning on items in your home, in restaurants and even theme parks. It can be found on thousands of consumer goods sold at department stores nationwide.

This warning is the result of a law passed in California in 1986, referred to as the California Safe Drinking Water and Toxic Enforcement Act of 1986 - more generally referred to as “Proposition 65" or "Prop 65" for short.

What is Proposition 65?

Proposition 65 is broad law that applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into California. It mandates that the Governor of California, through the California Office of Environmental Health Hazard Assessment (OEHHA) maintain and publish a list of chemicals that are known to cause cancer, birth defects and/or other reproductive harm. The list, which must be updated at least annually, includes a wide variety of chemicals that can be found in many everyday items, such as dyes/colorings, solvents, drugs, food-additives, by-products of certain processes, pesticides and tobacco products. The purpose of Proposition 65 is to ensure that people are informed about exposure to these chemicals.

Proposition 65 also requires warnings to be placed on any product, product packaging, or literature accompanying a product that contains or may contain any of the 850-plus chemicals that OEHHA has listed. As noted below, many of the elements listed under Proposition 65 have been routinely used in everyday consumer items for years without documented harm.

A warning must be given if the listed chemical is merely present in a product unless a business demonstrates that the exposure it causes poses “no significant risk.” The “no significant risk” levels established under the law present some of the most conservative public health levels in the world. With respect to carcinogens, the “no significant risk” level is defined as the level which is calculated to result in not more than one excess case of cancer in 100,000 individuals exposed over a 70-year lifetime. In other words, if you are exposed to the chemical in question at this level every day for 70 years, theoretically, it will increase your chances of getting cancer by no more than 1 case in 100,000 individuals so exposed.

With respect to reproductive toxicants, the “no significant risk” level is defined as the level of exposure which, even if multiplied by 1,000, will not produce birth defects or other reproductive harm. In other words, the level of exposure is below the “no observable effect level,” divided by 1,000. (The “no observable effect level” is the highest dose level which has not been associated with observable reproductive harm in humans or test animals.)

Why does Comic Shell include this warning?

Answering this question requires some more context. First and foremost, Comic Shell strives to comply with all applicable laws, including Proposition 65. With the way Proposition 65 is structured, however, it is not possible to ascertain with 100% scientific certainty whether or not a particular product requires a warning for any one of the over 850 chemicals on the Proposition 65 list. At the same time, the law allows any private person “in the public interest” – so-called private bounty hunters – to sue companies to enforce the law, and to keep a percentage of the penalties imposed. The law’s lack of certainty about when to warn is often exploited by these bounty hunters, who file thousands of Proposition 65 lawsuits every year. Penalties can be very high; the cost of defending a case also is very high. As a result of the potential penalties and the current private enforcement climate, Comic Shell, as well as many other manufacturers, have elected to provide the Proposition 65 notice out of an abundance of caution in order to ensure compliance and avoid the potential for liability.

The warning does not mean that our products actually will cause any harm. Moreover, a Proposition 65 warning does not mean a product is in violation of any product-safety standards or requirements. In fact, the California government has clarified that “the fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.” The government has also explained, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.” (

We believe our products are not harmful when used as designed. We provide the warning in order to comply with this California right-to-know law.

I purchased this product outside of California. Why is it included?

Our products may be sold and shipped nationwide and globally. Therefore, to ensure compliance with Proposition 65 requirements, we have decided to include these warnings regardless of destination.
