Rotors

I once accidentally bent a front wheel rotor after removing the wheel from my bike. I was surprised at how easily it was damaged...
I am sure they will be happy to sell you some brake pads, too
Part of my toolmaker apprenticeship, I work 3 month in heat-treating (different department) and a year in grinding section of the toolmakers.
When we left grinding stock of part to be ground either coming off the lathes or mills, or both, depending on parts, some needed considerable grinding stock left on.
Case Harding was the most complicated since it took days in an atmospheric controlled oven to get 0.030 deep. You didn't want to take more then 0.015 to clean up.
Wasn't unusal to loose parts to heat warping them and they would not clean up.
But yes, parts can be damaged.. I have two standard rotors hanging on the wall in the garage in VA I have used for reference in question on here. They seem pretty strong just handling them.
Now there not that fancy floating rotor.

I'm no toolmaker, nor do I have vast experience working with metals... I wasn't commenting on heat or atmospheric pressure..
I was only commenting on that if not handled carefully, a rotor can get bent/damaged from an impact...
My front rotor bent after the wheel tipped over, banging against the metal leg of a sturdy work bench on the way to the ground.... Fluke?... Perhaps....
I treat them gently ever since....

When I retired in 2012, I had a boxes of bike parts going back to the 70. With time on my hands, I started clearing my garage on ebay.
Actually got to be a lot of work and I was making weekly trips to the post office. There was this one lady who never left her chair.
Depending on delivery location, you would throw the packages toward 4 large metal cage bins.
I tried to avoid her. One day I ask one helpful employee did they ever payoff insurance damage.
He told me rarely. Mostly just if they lost it. And that was rare. Occasionally packages getting misdirected would show back up or maching damage would remove address for tracing.
And I kid you not...for damage, they simple wrote on claims item was not properly protected for shipping.
Interestingly, I used two accounts on ebay. Mine and the wife. I never had a issue with hundreds of items.
First poster's package looks boxed. Setting on a bubble wrap shipping envelope wrapper and I would assume another in between rotors.
And if shipping damage is an issue, the person who sent it is the responsible person and why he pays for tracking and insurance. Now if the postoffice tells him he didn't protect it, he owes the first poster new parts and he eats it.
Now one may get between a rock and a hard spot making that work out for them.
