got Dry rock from Amazon, what you think?

Got the rocks.
They are not the same as Marco rocks (at least from the ones I got many years ago). I actually like these rocks better. I got them for $37 instead of $50, must be from a customer return. I power washed them and not that much sand came off. I think most of it already settled to the bottom of the box during shipment. Packaging could be better I think.

Are they made in China? lol

I've gotten those and used them to create a rock wall. To do that I had to make coarse (2-4") rubble. They were fine and hold bacteria just as any other rock. They just didn't have the texture I like, and are as dense as concrete in the interior when you bust em open.
I can't remember exactly how they were packaged but I think it was rocks inside a plastic mesh in a cardboard box. Not much to dampen the road bumps
