These are previously recorded cassette sound tapes. They come in plastic cases. As a bonus, there are 2-3 popular albums from the 70‘s or 80’s recorded on each & listed but could be easily erased and recorded over. I have not been able to play these cassettes for a number of years due to my machine not working but the tape was in good shape with a quality recording at that time. For these reasons, there can be no guarantee or warranty that provides a return or refund.
