I couldn't find the Obi yesterday but I found one today, although I can't really read it:

It does say 株式会社メディアリング and maybe King Record under that, but I can't read whatever comes before them.
Finding a readable Obi (either for this or KICA-7009, which I suppose is the same) would help.
EDIT: I've linked them to media rings in the meantime since that's probably more correct.
