The original protective film is still on back side the tablet itself, and I put another front protective film.
Once you remove both films, it will look like new.
Function is all normal. I got an Ipad pro tablet, so would like to sell this one.
I also wanna give away extra accessories that I bought separately from Amazon, which include a purple case (it's been used for a while as protection, so don't expect the case will look new), and two front protective films.
The pen and charger are all there as photos.
