Heh, I know you are trying to be informative, but I have to wonder what kind of reinforced kevlar box would have been necessary to prevent my package from being crushed by whatever process brought enough force to bear on that box.
I remember when we made NIH begin using break resistant glass and plastic flasks and flagons to ship around viruses and diseased tissue samples. They simply couldn't get it through their heads that glass breaks! They were astounded at the need to separate items with cushioning and cardboard.
They were people with multiple doctorates from the finest institutions of learning on the planet, so don't feel bad about it.
I am being helpful. Now, you can be helpful. Demand that safe packaging methods be used. Don't think anybody in the post office, or the common carrier who actually moved the shipment, wanted nasty red stuff all over the place. You want to clear a post office in 10 seconds flat, holler "it's drippling blood" ~ yup, USPS handles that stuff. The other guys avoid it like the plague!
