27 Used Sony & TDK Audio Cassettes (HF-ES, HF-S, SF-100)

A lot of 27 vintage audio cassettes from Sony and TDK, models HF-ES, HF-S, and SF-100.
Based on notes found in the same storage box, these tapes likely date from the 1960s–1970s.

I tested a few samples by playing them in a cassette deck: all contained previously recorded music, likely recorded from radio broadcasts. No further testing was done.

Because I cannot verify whether these tapes can be over-recorded, they are listed as “defective” and are sold as-is, with no guarantees regarding condition or reusability.
