Slowakische Kassettensite mit allen Einlegern

Thanks! Yes, that looks like an Audio Magnetics shell. It doesn't have the typical black slip sheets which are cut in a way that they are visible at the sides of the window. It's just the simpler shell version without fixed window and without screws. The surface texture in the lower (thicker) part reveals it as Audio Magnetics.

So yes, you can write as you suggested.

Some of the more common Audio Club cassettes on that other site:

Among these, the red one is weird. I have never seen these anywhere, despite the description being in German only. There are no influences of Magna. The cassette and packaging are from Audio Magnetics (Portugal).
All the other ones there are typical Magna OEM cassettes.
