Thanks for the review! Ive been curious for the pentel. I have been using this Kuretake with Speedball Ink (which is water proof), works perfect, and have done so both refilling cartridges and with the platinum converter, no problems with clogging. The ink that comes with the pen is a bit bluish in my opinion, speedball is black but less darker. Also tried it with Carbon Ink but this ink takes a bit to dry, so I prefer speedball so far. You can check examples of drawings here: https://plus.google.com/u/0/118068221752550925627
Also have the Kuretake N8, thanks to Louie del Carmen's recommendation, and its just like this Kuretake you review (which I think is N4) but the 8 is longer. The bristles and construction seems to be the same except for the longer exterior and its way cheaper. I do prefer n4 cause of its weight.
