So I decided my first round of figuarts will just get stashed until I get all the line. But would a plastic bin with a lid be a good dusts and moisture block? My buddy said doing that and wrapping in bubble wrap is the best idea
Container Store has some good plastic bins for boxes. I store all my sealed stuff in their plastic boxes along with some bubble wrap for added protection.
If you're storing them in the basement, please be cognizant of your basement's temperature. If you have a lot of temperature changes down there you may want to store them on the main floor or higher. Humidity and moisture in basements will eventually affect the boxes.
