California Residents Prop 65

California's Proposition 65 entitles California consumers to special warnings for products that contain chemicals known to the state of California to cause cancer and birth defects or other reproductive harm if those products expose consumers to such chemicals above certain threshold levels. 

Below is an example of a Proposition 65 Warning label you may see on the packaging of your products.
