This is the Shichida Method's CD-included memorization series, "Haiku." By repeatedly listening to the CD, the haiku are designed to naturally enter your mind. Purchased about 4 years ago, and hardly used in the last 2 years. Stored at home (no pets, no smoking), so I am selling it. Condition: Some signs of use, but no writing or stains, and overall clean. CD: Audio checked and plays without any problems. Retail price: 2,000 yen (excluding tax) Will be packaged with bubble wrap for shipping.
