Finished Goods Storage (PCBAs)

What is everyone using for assembled circuit board/finished good storage? I'm looking for ideas.

Most of my assemblies will have some sort of wire pigtail soldered to one side of the PCBA, so they won't sit "flat", and I'll have a large enough variety of shapes and SKUs that I don't think any sort of custom solution will be economical.

I'm leaning towards plastic ESD totes with "layers" of PCBAs separated by an appropriate ESD foam. I do run no clean without washing though, so I'm not sure if foam will be a good idea given the possibility of contamination over time and the need for replacement.

TIA!
