Better than the 2 flap top manila cardboard boxes that I was referring to; nice white finished box with a single flap that folds into the box.....
As for no wasted space; pick your size, and add or do not add whatever packing or cushioning materials you want. The 4" x 4" series can be used to fit just about any O scale car, etc.
But the principle remains the same - pick a standard and your storage becomes easier for organization.
