There are some creases on the CD cases. I purchased these about 15 years ago. We listened to them many times at home, and this is how I developed my listening skills. Please refrain from purchasing if you are uncomfortable with items that have been handled by others. I welcome purchases from those who are okay with used items. The appearance is the old version, so it looks old, but it plays properly. Perfect for listening at home. The original box is not included; I will put them in the cases shown in the photos, take waterproof measures, and ship them in a cardboard box. Please comment if you have any questions.
