used microcassette tapes.............1 mc-60 at&t which is labeled as a message cassette but do not think the application matters.........1 panasonic mc-60..........1 panasonic mc-5......that is a rare 5 minute tape.......& 1 sony mc-30......the panasonic mc-60 has damage on the b side ..there are cracks in the plastic on 1 side......still rolls the tape around....this 1 is considered free....they all have some surface scratches on them.............you get 4 tapes per your purchase......if there are any issues with other than the free 1, get free returns but they seem fine.......
