If you carefully cut around the seam where the top flap tucks into the side, you can preserve the shrink wrap.
And then you can make working copies of the disks and seal them back in the box, like with a tiny piece of invisible scotch tape or something.
If you're careful, only the most careful observers will know
.
Definitely a neat find nonetheless! I never played it while I was young, but I did play with the son of one of my friends on his birthday earlier this year when they unpacked their old Mac Plus (with a ***working*** Hard Disk 20!).
Good luck!
