Sheaffer Valor/acrylic Pen Post Marks

[perth]

I posted this in the First stop section, but it has yet to be answered. If this is in the wrong place, please feel free to move it.

 

Hello. I've just gotten my Sheaffer Valor and have been using it for a few days at school. I haven't been doing anything that may have caused it like running around or dropping it, but there seems to be a faint mark on different parts of the acrylic pen. I suspect these may be capping/posting marks, as they are in the right place and are in ring shapes. There is one directly below the nib, one on the upper body and one at the very tip.

 

If a fellow owner of an acrylic pen could assist in identifying these marks and any potential tips on maintenance and perhaps a solution to this, it would be greatly appreciated.
