Query: To be honest, I'd just rather not get cancer...

Though I didn't even open the package, the protectors looked as if they were made out of paper. The kicker was the sticker on the unopened product that reads "California Law Requires This Warning: This product contains a chemical known to the State of California to cause cancer, birth defects or other reproductive harm." Thanks, California!! You forever have my gratitude.
