Set of 8 cassette tapes, for chemistry and English educational materials. - Quantity: Set of 8 - Title: Chemistry 8: Reactions and Separation of Cations - Title: English I: 60 Memorization Selections These came out of my parents' house as educational materials. The textbooks and files were unused, but I discarded them. I heard that cassette tapes are valuable, not as educational materials, so I thought maybe you could dub them if you cover the tabs with tape? I don't know the details, but I saw it on TV! I don't know how long the tapes are. Thank you for looking. #cassettetape #ShowaRetro
