A while back I’ve moved and ended up relocating on the other side of the globe. I had quite a bit of trepidation moving all my miniatures. I use a fast and loose way of storing my figures in plastic boxes, layered on bubble wrap sheets. Good enough to keep the paint job protected but only if the box is kept upright. If I dump it on its side, the figures are going to shift around. Throw in a bunch of jostling of the box and you can expect figures to be clanking against each other (and on the inner sides of the container). I totally expected that my shipped stuff would be tossed around like a beach ball, and stacked sideways or upside down in a shipping container that would make any Tetris player proud.
So I had to try to work out a solution and stuck with bubble wrap. Cutting small sheets, I rolled each figure in wrap with a bit of tape to keep it in place. The key is to make sure it’s lightly snug and not wrapped too tightly. For plastic figures especially, you can inadvertently bend or snap off fragile parts like rifle barrels so don’t wrap too tight. Some figures can even be wrapped two to a sheet, particularly prone figures by having the bottom of their bases facing each other. I dumped them in hard plastic containers, sealed the tops in packaging tape, and was good to go.
It did take some time. Don’t expect to do this in a night. Set time aside to do it. At a leisurely pace, I was able to get about 300 figures completed in a week. I cranked out a lot of figures just watching TV an hour or so a night. You certainly want to get this on your to do list for early packing though. Vehicles and tanks were done similarly, but I made sure to remove turrets and wrap them separately.
How did they ship? Just fine. Granted you have to be prepared to snip tape and unwrap a ton of models (more things to do while watching movies). But I can say my figures, both metal and plastic, made it across the world in one piece.
So if you have the time, consider this a solution for packing your miniatures. While you can buy expensive cases that can keep your figures snugly packed individually in foam it can be costly. For a budget (and a ton of models), wrapping minis in bubble wrap is a cheaper workaround.
