New battery: a battery has been replaced in the Apple Store, and charged only once for testing.
New touchbar, new keyboard, new trackpad, and new bottom casing: these parts have been replaced during the Apple's battery replacement service.
All original packing materials included: box, manual, dust cover.
Apple genuine 87W charger included.

The MBP has been used in the clamshell mode with an external display, which means I rarely used the built-in Retina display. I have not identified any minor issue with the display. The top casing is also in mint condition as it stayed on my desk 24/7, and the bottom casing, keyboard, touchbar, trackpad have been replaced to new ones during the battery replacement.

Good luck!
