Query: Sturdy Holder for my .308 Ammo for range

I buy .308 in bulk normally, so packaging is loose, or crappy, or in large ammo box. These Cartridge Holders are very nice, ammo easy to load and unload (to and from box), lid has yet to break off, and great for taking to range or just storage in prep. for next range trip or the coming Zombie Apocalypse.
