I bought this set of USA-made Channellock nut drivers:

Sharp eyes will already have spotted what I'm talking about, but here's a closeup:

All the drivers that are pointing downwards in the package have shed what appears to be rust into the packaging. There is no rust evident on the chromed exterior of the tools, so I swabbed the inside of one of the hollow shafts, and that is indeed where the rust is coming from:

I'm not particularly concerned by this. I'm just going to give them each a shot of WD-40 up the shaft and swab them out, and they should be fine. But I do wonder how this happened. Surely Channellock wouldn't display them this way if they were expected to shed rust into the pretty package. Do you think they were stored in a damp and humid environment?
