Samsung S21 5G Pre-owned
I bought this phone for a friend who needed a second one for personal use besides her work phone and did not want to spend a lot of money for a new phone yet. It looks like brand new no dents, no scratches anywhere on the phone. Front display is perfect, sides of the phone and back of it are perfect. Turns on perfectly with no issues on Google, Samsung, or Android. Cameras work great both front & back. I tested it before gifting it to my friend and haven't heard any complains from her yet. Phone has a screen proctector.

Galaxy S21 in perfect condition!
Came exactly how I expected, if not better. I bought the same device from another seller and it was scratched horribly, although the screen was good. The one I got from Best Buy looked brand new! Didn't come with a charger block, but I have plenty of those. Came with a cord and perfect condition phone! (Case not included but you can see there are no scratches on the actual phone–near the camera shown)
