Konica XR-I 90 cassette tapes As shown in the photos, this is a set of 4. I've never used cassette tapes before, so I don't know much about them. I would appreciate it if you could look at the photos. - Brand: Konica - Model: XR-I 90 - Type: Normal Position New, unopened. Stored at home for a long time. Since they are unopened, I think they can be used, but I cannot guarantee it due to the passage of time. If you understand the above, please consider purchasing. #ShowaRetro #HeiseiRetro #CassetteTape #Konica #RetroBoom #Emo
