Love love love the book and fortunately there was no permanent damage, but the box was soaked from the rain on my front porch. I opened it up and there was literally water on the books. I dried them off and kept the books closed and put them in front of my dehumidifier so I was able to use them both but I would suggest books or things that could get damaged by water or inclement weather should be perhaps wrapped in a plastic bag so that if this happens the product is still protected. I have also had packages delivered in the past that would be out in a plastic bag at delivery but that would be the carriers responsibility.
Wanted you to know, but the end result was still good.
