Apple iPhone XS Max .. with 2 protective covers

iPhone XS Max has been erased and is unlocked .. color is gold and shows no wear except hairline crack that I’m pointing to in photo … it’s been like that for over a year and I just haven’t taken it in for replacement … does not affect use of phone at all Includes 2 cases shown. Black one is silicone and marbled one is hard plastic. I’ve been using both. No signs of wear to protective covers at all 64 gb capacity
