I think the correct answer is "without anything", meaning without the clear plastic jewel case.
But since I own a few brand new albums, including Konami Sound Catalog Vol. 3, I can tell you it didn't come with a proper shrinkwrap/seal, but inside a resealable baggy. So I think at least some of them came that way from the factory. Yahoo Auctions should be of good help, just look for brand new 8 cm discs to see how they are packed, and bingo:

and to make sure it's not the seller or the shop who added the resealable baggy, look for original stickers:
