Not sure if everyone knows this but...
(I think) The limited 800 and 1000 yen MOON/blossom versions have different packaging. "紙ジャケット仕様" is referring to the fact that this will be packaged in more of a paper slip case sort of deal. Not the normal plastic packaging.

Like this.
And then the "booklet" is inserted into that.
Not 100% sure though.
Unless it means that the booklet is just folded and inserted into the paper jacket like the serial numbered cards and such, which is then packaged in a plastic case. *shrug*
