That CGC packaged your submission, after happily taking your money, in such an incredibly crappy way is ....
I'll also mention that I, and I imagine many others folks, have received shipments from CGC that contained one slab of 25 that was damaged, as you show or worse. Since the remaining 24 slabs were not damaged, I "assume" that the slab was shipped to me in that condition, especially since the comic books were packaged relatively secure. For what purpose that was done, I'll leave alone for now. All such comic books were ME and, thankfully, arrived undamaged the second time.
