Instant purchase is welcome, no need to leave a comment. This is the "Ultra-Slow Method English Pronunciation Training" book. The CD has been opened, but its functionality hasn't been tested. There are no writings or underlines. Please refrain from purchasing if you are sensitive to used items or desire a perfect product. I will package it to prevent water damage before shipping. I bought this intending to study, but I've started decluttering language study books that I don't use. #DeclutteringAndBecomingAMinimalist LanguageStudyBooksForSale
