Sounds like "brown pouch" was the deal breaker.
I ship in USPS priority boxes and so far no crunched plants. Most stuff goes in a damp towel in a zip lock and that in a plastic bag.
Very delicate stuff like Downoi, I send in a deli container , then in a zip lock.
My vote for best packaging goes to Speedie408, Nick's shipping mgr. is the best. Also, very good at shipping is ohbaby.
