Who says that the media has to be disks. Dig around for some dusty old
paperbacks. AFAIK, the container does not have to match the contents.
That being said, I've never been challenged on a metered (i.e. prepaid)
Media Mail package.
This reminds me of the times I was shipping a tuba via Amtrak Express in
a large fiberglass case. There was a size exception in the shipping
rules for musical instruments, but it didn't apply if one was shipping
empty cases. So my customer scrounged around for a beat-up junked
trumpet and put it in the tuba case. The stationmaster didn't have a
problem with that...
