Yeah, yeah obsolete technology. Still. Has anyone found a good storage means for floppy disks, specifically 3 1/2 inch?

I was messing around with one of my clear EU DS cases and found that each holds 3 of them very well in the clips. But, I imagine there must be an even better way to store those old things and look nice alongside my other games.
Could they fit in the sleeves of the Poly Cases, in place of CDs?
I know that for old PC games, you could just copy the contents onto a CD-R to accomplish the same task, but I wonder if there's a good storage solution for the original disks.
