I found a nice storage container at JoAnn Fabrics. The brand is Lock-Ups, and they come in a handful of sizes. I got the 8 oz and was able to fit all of the base game cities and figures in it. I think you can easily fit the cities and Volkare in one and the 5 hero figures in another. They won't bounce around too easily and I think the Lock-Ups are a sturdy container.Here is a link to the container on Amazon so you can get an idea.

It's really expensive on Amazon and really cheap at JoAnn's I paid .97 for it, because it was 40% off.
