This is an English conversation教材 for adults that incorporates the Shichida method of education, famous for its right-brain development approach. The main feature is that "by listening to 'this' and repeating it for just 20 minutes a day for 60 days, you'll become fluent in English." While I'm not sure about fluency, it's true that you'll memorize things by listening repeatedly. How you utilize that is up to you. Since I only listened to the CD audio on my smartphone, the product itself is in good condition. Please refrain from purchasing if you are looking for a new item.
