SKC QX - 1987 - EU
SKC made many tapes for other companies, like Memorex and their quality was always good and sometimes, exceptional.
But they also made their own cassettes, but these were never really common outside of Asia.
Here is their Fe/Co Type 2 from the late 80s.
The shell is very nice and Denon / Sony looking, with that big window.
The tape is very good, as good as an XLII / SA of the same period.
*Please note* That although new and sealed, the print on the foil wrapping is starting to blur after 30 years and there could be remnants of the outer clear wrapper on the foil.
