My book selling has been a natural spin-off of my love of estate sales, thrift stores, and yard & flea market sales. I look through every book, and note writings, tears or rips, so that I can honestly inform you, the customer. Since I do not know the books history, I cannot confirm if a book was from a smoke free or pet friendly source. Most used items will come with some kind of smell or another. If you are sensitive to any odors, please don't purchase items from me. Like many sellers on ebay, we try to make customers happy. If at all unsure, ask before purchasing an item from me. I will be more than happy to respond. Thank you for reading this.
