We have a great selection of these books which are really expensive to buy. These audios are checked when they are returned and many are coming back dirty with finger prints and lots of scratches. They can be washed but the scratches on them cannot be fixed. Please be careful when taking them out so that we all can enjoy listening to these stories with no skipping CDs. Please do not attempt to clean them yourselves because they are delicate. Thank you for your understanding.
