Are these Apple refurbished, or bought from a third party like Best Buy or Amazon? I’ve bought plenty of Apple refurbished products (directly from Apple) over the years and they always look like new (including 100% battery health).
Third parties and resellers though I’m convinced just call their returns/open box units that appear to be in decent condition “refurbished.”
Admittedly this was a few years ago. Has apple mended their ways or are they still on the "used car salesman" grindset?
