Yeah, the Ridgid ones are somewhat watertight (have a gasket and clamps) and built fairly stoutly. Overkill for what I use them for.

The critical feature for me is the cups fit flush with the lid. So anything bigger than micro parts can't migrate across the box, when in transit.

I'm guessing you're talking about these? https://www.harborfreight.com/8-bin-portable-parts-storage-c...
