Back in May I came across a site in Australia that makes foam inserts for tool cases.
As I really needed something to carry my figures around in I jumped on this double time.
The tool case I purchased from a large hardware warehouse franchise here in Australia. I gutted the insides so that the foam would go inside.
The foam inserts come in two main types: infantry and cavalry size. I ordered the infantry size ones, and four of them promptly arrived. The case itself holds four layers with a foam cover layer for the top.
