California Proposition 65

Attention California, USA residents 
California's Proposition 65 entitles California consumers to special warning 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.  We know you are concerned about product safety, and we are taking all necessary steps to comply with all applicable safety and health requirements.  

If a "Warning California Prop 65" link does not appear at the product page for the product you wish to purchase, it indicates that it does not require the CA Prop 65 warning.
