Unopened Ricoh Entrance Exam Intensive Lecture Set, a set of 8 cassette tapes for the Physics course. - Brand: Ricoh - Model Name: Entrance Exam Intensive Lecture Set - Contents: Set of 8 cassette tapes - Course Name: Physics 3: 2D Collision 2-A - Intensive Training Content: Entrance Exam Preparation - Quantity: 8 tapes - Condition: Unopened - Packaging: Plastic This came from my parents' house as educational material. The textbooks and files were also unused, but I discarded them. I heard that the cassette tapes themselves are valuable, not just the educational material, so... I heard on TV that you can make a copy if you cover the tabs with tape? I don't know the details. I don't know how long the tapes are. Thank you for looking. #CassetteTapes #ShowaRetro
