err,blasterion, what is nr. edition?

oh sorry, I meant something like first press, second press, etc.
but I don't think this happened with her first singles yet..I think?

I hope someone has the answer to all of this :)

As said, I think the cases are only to protect them.. I mean, there is different cases for them, mine has some "Keep CD single" mark on it, but those pictured doesn't.. So I don't think it's a first press, just something added by the owner..
