This seemingly insignificant box used to be sold by Apple and contained ten single-sided floppy disks. Those were meant to be used in a Macintosh computer. I had a bunch of them but somehow managed to keep an empty box. It was a great time.
Each floppy contained a whopping 400 KB of storage for a single-sided version. At one point we could get them for 70$ a piece. It was expansive compared to 5 1/4 inches flexible floppy disks that contained either 160 KB or 360 KB that were typically used in IBM PCs. From a design perspective, Apple’s floppy disks were rigid, smaller, sturdier and dust proof, hence a higher asking price.
