Thank you for viewing. Yuhobika April 2017 issue, bonus CD: Singing Ring Singing Ring CD, effective for stress reduction, with healing sounds proven by brainwave analysis. I listened to it, and there were no skips. The CD has a few small scratches. The CD sleeve has stains, folds, and scratches. As this is a layman's inspection, I may occasionally miss something. Please check the images and purchase with your understanding. Thank you.
