This is a bundle sale of business books. Thank you for looking. As they have been stored at home for many years, there is age-related deterioration. Some books have signatures. There are stains, tears, and folds on the covers and spines. There is writing inside. *There may be stains and writing in addition to what is shown in the photos. This is for those who are okay as long as they can be read. Individual sales are from 400 yen (price varies depending on the item). Packaged with plastic only. I have a dog. The books were stored on a bookshelf and have not come into contact with the dog. I will take sufficient care, but pet hair may be mixed in during packing. Please consider this purchase with the understanding that it has been stored by an amateur.
