James,
Glad you're happy with the bag, I appreciate it! If for some reason that support piece doesn't go back to normal, let me know and I'll take care of you. I hear you on the shipping but unfortunately, the envelopes are too thin and I'm afraid the bags will either rip through them and fall out or the buckles won't have any protection and get busted. That said, I'm waiting on USPS to deliver new regional boxes (they lost them) to me, they're a bit "squarer" and should allow a gentler bend.
