OK... Box has been photographed, opened, photographed again, contents thoroughly evaluated, reading material skimmed, selections made, selections photographed, replacement items inserted (which required three attempts at packing - involving placing many of the smallest items in a small candy tin), and at some point this morning, will tape, label and send on the next leg of its journey.
note to nlerner: I expect this is likely the third (or fourth) time this box has been used. You WILL need a new one.
It isn't "full of fishing sinkers" heavy, but you could call it that.
My suggestion is to not rip into the box with a drywall knife.
a few useful items selected, and earmarked for accessorizing fleet members... a few items I won't need until the next impulse purchase inserted, and the epic "Box Saga" has survived another chapter.
