Gallon Ziplocs with folded over cardstock sheets for labels, also keeps them rigid so bags of cables that aren’t full don’t get buried. I have two bins, one with common stuff in my office and the other stays in the basement with all the weird cables.
Clear plastic bins and reused cardboard boxes.
It used to be just boxes, but some of them were disintegrating after 25 years.
I’ve a feeling that my collection is substantially larger than y’all’s, and that mine gets rotated a bit more frequently.
