Rtm 90 c. Cassette
Excellent case. And massive inlay for jotting down Ur. Tunes recorded tapes themselves are. Nice clear plastic with strong screws fixing and nice. Big labels. Great value as well for a complete mystery buy. I've never seen before 👌

Excellent quality tape
RTMs ferric tapes are made to the same specifications as the old BASF LH, used by recording studios across the world. I’m absolutely delighted with the quality of these cassettes, zero dropouts and excellent frequency response, high output and good noise performance. In my tests with these cassettes, I’m using my Denon DRM 710, 3-head dual capstan machine that also benefits from Dolby HX Pro and adjustable bias. If you are buying RTM tape, you can be assured of a high-quality European made product. This review is written by genuine customer based in South-East London.

Broadcast quality, as far as cassette could ever be.
Good quality, but the C60 is even better.

Mwaaaah... the French Cassette Tape has always been celebrated for its excellence...
Much lower noise than any of the other blank tapes I have, and perfect frequency response as far as I'm concerned. The visual design is also fantastic. The only issue I have found is that the cassette itself is prone to receiving scratches - my own player has scored lines in it from every time I have inserted it that I can see when light glints off them. Nevertheless, it's nice to see a high quality product manufactured on this side of the globe, and it's even nicer to listen to!

A good quality type I tape
As far as new Type I tapes go, these are the best on the market. With Dolby C, these tapes can absolutely sing in a high end deck with even the most demanding recordings. Not a sony metal master, but it's a competent tape and compared to the latest UR (that I had to return as they were borderline unusable), these were worth the money. Do wish there were a bit cheaper.

Quite good quality.
These record similar to a BASF LH-I. I have come across a few drop outs, so fast forward and rewind the cassette a few times, or, do a blank recording or two.
