10 x pure chrome, with a bit of cobalt, Type 2 cassettes. The tape comes from BASF.
You really need a deck that has calibration features to make the most of these, otherwise they sound a bit quiet and dull.
But if your deck has these features, and you record them at about 0db, you'll find these are as good a sounding Type 2 as you can get for this price.
Comes in their original outer box.
