This is a set of original textbooks from the University of Human Comprehensive Sciences and books sold in bookstores. Some were purchased by myself, and others were bought from flea market sites. Some books have highlighting with fluorescent pens and/or writing in them. Individual sales are possible, but the price varies depending on the textbook, so please comment first. Shipping methods differ for purchasing the entire set versus individual books. Please be aware of this. Please understand that these are used items before purchasing.
