There's some interesting shaped ones in the pile closest to her, not really washers I think. I wonder how they were collected/selected - picked up from the streets perhaps?
(I have an extensive collection of hard drive platter spacers)
The drice spacers make me think of my favourite stick of RAM.
In the 90s, I repaired Commodore Amigas, and I do mean repaired. Back then you'd de/solder replace chips, caps, anything borked on a motherboard.
In one case, it wasn't the motherboard, it was a stick of RAM that seemed borked. Wouldn't even boot with it in place, so I swapped it for a new stick, problem solved.
One day I was opening boxes of product, and my utility knife was MIA. Seeing as it was dead RAM, and it was sitting on the table, I used it to cut the tape on the box. It became my new box opener.
This went on for months, with hundreds of boxes cut open.
Typically I'd just leave it my pocket. All day, home to work, just hanging out in my pocket.
One day at home I needed the pocket space, and threw it on a table. It sat there for months, got wet (spilled beer, drinks), was looked at, touched by 100 people, and then I moved.
Months later, in another city, I had RAM die in my machine. So I dug it out and tried it, and it worked! And I proceeded to use it for another few years in that machine.
Was I mistaken in thinking the RAM was dead? Did the abuse fix it? Either way, that was strong RAM.
One looks like a combo tool that is a small spanner and a key of some sort. The triangular piece might be a tag. The long number 9 looking thing is interesting but anyone's guess, a lever of some sort? Little blue thing looks like one of those rubber faucet washers that comes in a variety pack.
A few non washer items mixed in that stand out are the 1/2 inch conduit locknut and what appear to be a few T-nuts.
That tri-spoked aluminum disk looking thing is also interesting.
