Apple iPod Nano 7th Generation Blue (16 GB), Used. Comes with accessories

This is a 16gb iPod 7th Generation iPod Nano in Blue. It has been used and there are a few scratches on the screen. It also has "pixel lines" on the screen when you turn it on. There is a way to remove the pixel lines but I am not good with technology, so I don't know how to do it.
