Bests & Worsts Reviews from Amazon

Product was delivered promptly, and appears to work effectively as described. My concern is that the back of my package contains medical cautions that do not appear on the package images accompanying the product details on the order page. I have attached a picture of the back of my package that warn of contact with the skin or breathing the fumes of the sticks and othere medical cautions. Why don't these warnings appear with the product on its Amazon order page?
