So to re-iterate, there can be evidence of light wear on the screen/chassis/back. The back cover can be in marginally worse condition than the screen.
Light wear – light wear becomes noticeable from distance and even more recognisable with closer inspection.
Indentations, dimples and depressions are acceptable, but chips and gouges are not permitted.
A small amount of paint can be missing, and light scratches are permitted.
