I like the approach for the cardboard storage.
Agreed its a hazards, ditto in drying them out though conditions are controlled and if they can survive in a garage in the South West, my temperatures are under 100.
I won't throw them out, but I do understand the risk. Definitely worth keeping in mind for anyone handling these.
I have put primers back in those trays before, ungh. This was a full 1000 of them, ergh. Don't have the patience.
