① Music Therapy for Insomnia (minor scratches) ② Music to Inspire Courage and Confidence (no scratches) ③ Classical Music to Enhance Concentration (no scratches) ④ Classical Music for Increased Efficiency (no scratches) (Released by Polydor K.K. and Victor Musical Industries, Inc.) Each item originally cost ¥2,000-¥2,300. I purchased these when I suffered from insomnia due to stress. I listened to them a few times before sleeping or during my free time, but recently I've been busy and they've been stored at home, so I'm putting them up for sale. The surface of CD ① has scratches, but it played without any issues. I would be grateful if someone who understands that these are used items would purchase them. I plan to ship them wrapped in bubble wrap.
