My 2018 refurbished 15" base model MBP was flawless when I received it. Packaging now looks identical to the regular boxes except it says "Refurbished Macbook Pro" on it. But as of cosmetics, they're no scratches on it or any signs of use. I'm not sure what my battery cycles was at when I got it, but as of now (owned it for 2 weeks), I'm at 10.
Regardless, I bought from Apple refurbished instead of through B&H (cheaper by ~50$) is because I didn't know if I was going to like it as an upgrade from my 2015 13". I wanted the ability to return it and B&H doesn't allow returns once you rip the plastic seal.
You sure about that?
