I tried my best to photograph them in good detail but they never caught my eye after I turned the unit on and got to drawing - so I'm leaving the screen protector so you can make the call about taking it off or not. Maybe it won't bother you. If it does, XP-Pen sells this very screen protector on their store site. Oh, and the current nib is the one that came with it and has lasted me quite well.All the other replacements are currently in the little container at the bottom of the pen case.
