"CD Book for Sound Sleep, Created by a Renowned Autonomic Nerve Specialist" Hiroyuki Kobayashi / Takeharu Oya Price: ¥1200 #HiroyukiKobayashi #Hiroyuki_Kobayashi #TakeharuOya #Takeharu_Oya #Book #Lifestyle/Household Thank you for viewing. The CD played on my home player. The book was kept on a bookshelf, and the CD was stored in a separate plastic CD case. The book has some discoloration on the spine and other areas due to aging. The CD will be placed in the case inside the book for shipping, so the plastic CD case will not be included with the product. Please understand that this is a home-stored item. Thank you for your understanding.
