Comments about Cross Cross C-series Fountain Pen Carbon Black:

The new cross c-series is really a beautiful fountain pen (especially the carbon one, my opinion).
In the good things, the size is excellent as the weight and it is a very comfortable pen to use.

On the other side, you just can not use it ! When I bought it, the ink flow was much too large and the paper was absorbing much ink making the writing very fuzzy. The pen goes back to Cross for repairs and comes back with a more reasonable ink flow (still fuzzy but better), on the contrary there are some disruptions in the ink making it impossible to use (in one word out of five you have to rewrite and rewrite until the ink comes back...). So I am going to send it back once again but they are going to higher the ink flow. So, back to the first problem.

I also contacted the customer center of Cross (which guarantees an answer within 48 hours). It was three weeks ago and still no answers !!
For the price, you certainly can get a better pen. It is a shame as it is a beautiful pen and that other pens from Cross (like the ATX works very well).
