RAKS SD-X - 1990 - EU - 3 Pack
Raks are probably the biggest cassette manufacturer you've never heard of.
Like SKC, you're more likely to find cassettes they made for "bigger" brands than ones they put their own name on.
Closely tied to BASF, they produced some fantastic cassettes.
This lovely Type 2 boasts a really attractive, well made, shell and sound as good as a good SA to my ears.
Very hard to find, grab one while you can
