Likely a slightly warped CD case with a grippy bit in the middle that’s undersized.
Which means the discs can rotate and then collide with the case. But key to the scratches is the undersized grippy thing, a good case won’t let your discs spin.
Cheap cases have been doing that since I was a kid and I burned my first CDs back in the day. Nothing quite like being the cool kid with a CD burner back in the day.
Oh this takes me back
