You might feel crazy. I have a friend who stores her wing minis in self- storage units. She has a huge collection of minis. Some are there with her. She used to take them in a Plano cases when she comes home. I have few ships with me, not too many, I used to keep them in a cardboard rack.
I think it is best to store in tackle boxes or art supply bins. If you are looking for cheap storing ideas then go with zip lock bags or cardboard box. Where do you guys store your minis?
