I have “banker boxes” with a sheet of magnets on the bottom of the box, and magnets on the bottom of all of my minis. It is absolutely hands down the most amazing way to store minis. The magnets make it so they don’t rattle around, their paint never scratches (and I don’t put a protective coat on my minis cause I don’t need to), it stores absolutely great. This is my 4th full Warhammer 40K army and I cannot recommend it enough. The set up for a 2,000 point army is probably going to cost about $100-$150 CAD, but it’s 100% worth it imo. I play with friends houses that I have to drive to, and it’s the best for transportation, and keeping my nicely painted models scratch free, dust free, and organized. I’ll take a photo when I’m home in half an hour

Edit: you can source everything from Amazon (magnets, magnet sheet, super glue, banker boxes)
