Just a quick separate pic to show how I'm storing my magnetized Ravager and Raider. The foam is a V2H tray from Kr Multicase, and you can fit 4 of them in one of their card cases.



As you can see, it's a tight fit (there is some room for optimization still) but I can have 2 Ravagers/Raiders in one tray. Since I have 4 Raiders and 3 Ravagers that even leaves some empty space that I'm reserving for 2 Venoms later, when GW releases the model (hopefully it will be small enough to fit).
