Mid 2015 Macbrook Pro 15, 2.2 GHz Quad Core Intel Core i7, 16GB RAM, 250GB SSD.
Model A1398.
 
Of the 15 laptops I had to sell, this is the only one that had an issue.  It was working fine for years, and then after being pulled out and getting ready to recommission to sell, I could not get the OS to reinstall.  The first thing I did with every one of these laptops was to wipe the hard drive and reinstall OS Monterey.  When I did that, it crashed mid way through.  I could not reinstall Monterey, so I tried to reinstall from USB boot sticks for High Sierra, Big Sur, Sierra, and Mojave, and every one of them failed right about half way through the install.  My gut tells me something is wrong with the SSD.  I can't think of anything else that might cause that.

Anyway, as you can see from the one picture, the machine will not boot anymore to an OS.  Perhaps swapping the SSD will fix it.
 
Other than the above, the laptop is in excellent condition.  It was used for a training class with 14 others, and kept in storage boxes between classes.  All machines were left on desktop and used in training, so little opportunity for being dropped, scratched, or otherwise.

Top of case had a skin on it since purchase to protect it.  We'll keep the skin on for shipping, you are welcome to remove, but we wanted to keep it protected during shipping.  Screen has no apparent blemishes or scratches.  Bottom has a couple of very minor smudges or blemishes.

15" 2880x1800 screen in excellent condition.  2.2 GHz Quad Core Intel Core i7 processor with 16GB RAM and Intel Iris Pro graphics.  250GB solid state drive, very likely damaged?  We do not know.

Laptop will ship with the 4 items seen in the picture with the box... you will receive the laptop, the power supply, the box as shown, and the laptop shipped in the bubble pack as shown.  Packing paper will fill the open gaps.  The box is 19"x12"x3" and the total weight is 6 pounds.

I have no method to perform battery tests, but the battery is taking a charge and holding.  These are 7 years old so I doubt you will get 10 hours from it, so please keep that in mind.  That said, they've been holding for the few hours I've been setting them up.
