I was thinking maybe a plastic ammo box or other plastic container with dividers for each caliber or for rifle and pistol mags. Right now all my rifle mags are stacked on a closet shelf and all my pistol mags are loose on another smaller shelf. I would love to have an way to organize and store them all neatly so I can find the mag I need a little easier. This is would also make it easier to take the mags I need to the range.
