It seems like most companies use boxes that barely meet the minimum of what's needed, and they lose at least some of their structure after one trip through the system. Plus shippers seems to be increasingly careless, which is probably the result of trying to shuttle a larger volume of packages than what they're resourced for. I don't even bother trying to ship guitars any more, and anything else gets an additional outer shipping carton that's brand new, heavy duty, double-walled. It's insane.
