JVC cassettes aren't common and so, they are quite collectible.
Musical performance is adequate with negative bias and Dolby NR, but nothing great.
JVC is very collectible and these are very retro looking, so if the looks "float your boat"...
Boombox enthusiasts love to display their iconic JVC M90s and M70s with either Reel cassettes or JVC branded cassettes. I agree! ;)
Note: There is only one available. Two small repairs on the wrapper with clear tape (no fingerprints on it), and some light scuffing. There is also a very visible 1.0cm hair line crack on the case. None of this would not bother me, but... to each his own.
