Portable Media Backup Kit

I'm currently in the process of assembling my portable media backup kit.  Any viable rewritable media will be stored inside of a styrofoam padded Mario/Zelda lunch box ^{minus thermos} which will then be placed inside of a small fireproof safe.  Not pictured are the other two-thirds of my backups, which are countless optical discs and a stack of hard drives. Just for the heck of it, I've already started collecting vintage IBM laptop hard drives in case I want to restore some old computers.
