I'm amazed it made it. The top center pull knob came unscrewed at some point. So the screw and washed were shaking around inside the glass the whole time. The real danger was the knob itself. It has more weight to it and could have smashed the whole thing. Luckily FedEx/USPS didn't shake it to hard this time around.
Once reassembled, it's as expected. Glass container with a copper plated steel lid that seals quite well. I have the whole set now, but the 2L was the only one worth buying from here.
