Here are three of these screens in a row. They are really quite small. The displays are available to buy at AliExpress.
In terms of packaging, it was quite poor, just shoved into the box with some bubble wrap on one end and foam packing in-between each screen. At least they arrive intact.
I ordered 6 of these for redundancy. The connectors are a little bent on a number of them, but I'm sure that won't affect their performance once they're soldered down.
The build quality seems quite good however.
...and finally a printout of an example circuit board with the LCM overlaid on top. It actually aligns completely, the photo is a bit off because the connector on the LCM is not perfectly straight.
