21 reloadable cassettes; mostly Kalt brand, some Kodak, a few plastic. All well used but still usable. I tested them as follows: put all in a shoe box, shook reasonably vigorously for 10 seconds, and confirmed that none came apart (perhaps that should be a new ISO test standard). None the less, assume there will be a couple you are leery of using for one reason or another. $10 shipped first class (no tracking) in ConUS. $11.50 via priority mail with tracking.
