I hope you didn't smurf up.

Oh my god, this gift is awesome.

No news is good news?

How are you supposed to open it? How does it exist in the first place?
The force of gravity pushing on the top half would make it slowly push out of the side, until the weight of the half on the side tilted and hit the table. The top half would still be trying to push it out slowly, but the resistance of the case on the table would make the empty box move backwards slightly to allow the case to continue to move out of the portal, but since portals can't move and they are mounted on the box's wrapping the portals would cease to exist as soon as the box moves. Which would cut the case in half (approximately, depending on how far it's moved before it tilts and the box moves) and probably the cd as well. Pieces of the bottom of the top half and the top of the bottom half might even be fused with the wrapping, which would be even more inconvenient.
Unless you somehow found a way to make it suspend itself in midair like that, to which I say bravo; but I think it would be very improbable to make it stay there without a PHYSICAL outside force. So you'd have to glue it to the portal or something. Which means you wouldn't be able ti pull it out anyway without moving the box, thus resulting in the case being chopped in half again by the sudden destruction of the portal. But it's the thought that counts, right?
