I'm glad to see the packaging made it around the world. Oddly enough, I package that stuff the same way even if it's going 50 miles away.
The packaging photo of the 4 cuft flat pack worries me a bit. Looks like it shifted a good amount and got close to the sides of the box. The cubes are a new idea I had for packing up the sub boxes. To make sure they protected good enough, I wrapped the first sample 4cuft flat pack up with the corner protectors, filled the box with the cubes.....and literally threw the 70lb as far as I could. Picked it up, threw it again, then dropped it chest high directly on it's corner. My friend wanted a try and spun around like he was doing shot put in the Olympics and threw it a good 15'. No damage. They passed the delivery test.
I think the delivery guy would have to purposely do something to damage them.
