Haha. I had the same thought. Mine was also folded in small mailbox.Congrats! Got mine today
Bit annoyed that after $630 fee(which the govt long ago promised to abolish), multiple formalities and many months of wait, the piece of paper all this was done for was casually folded and stuffed into the tiny mailbox haha They should really mail it in 'do not fold' envelopes. Better yet, provide digital copy (hopefully soon someday)
