This is a set of music CDs featuring Koji Tsuruta and 12 popular songs by male singers. I used these for karaoke practice. They are used, so there may be scratches and folds that are difficult to see in the photos. All songs are sung by the original artists. The cases and discs have some scratches and show signs of use. They are not in pristine condition, but there are no problems with their use. The Koji Tsuruta CD does not have a booklet. The lyric sheet has many folds. Please purchase only if you are satisfied with the condition. Feel free to ask any questions!
