Iphone 12 pro

I ordered an iPhone 12 Pro, and I bought the "good" condition. When it arrived, the phone looked AMAZING except for 2 little scratches on the screen (as expected). The funny thing is, when I was taking off a screen protector that I put on it (I messed up with it), a SECOND screen protector came off as well! The two scratches that I saw were on the screen protector that was already there. I have no clue whether or not the pre-owned put that protector on, but either way, I got my phone in amazing condition, with the added bonus of no scratches on the body or the screen.
