Avoid, poor quality pens
on 10 July 2016
I and several friends bought these pens to work on our third year, geology degree mapping assignment.
All of us found periodically (in my case within the first hours of use!) that either the pen nib dried out very quickly whilst in use or that the nib became damaged easily.
The ink is also NOT Fade proof and does not work very well on top of pencil coloured sections. If it were only my pens that experienced this, I would of put it down to just bad luck. But several people experiencing the same issue with pens they bought at different times, from different merchants?
