There is one problem with these pens and that is the nibs. When really juiced up, the nibs will have a tendency to crush sideways as you write, especially when pushing down to pump the ink valve.
Simple solution: Measure out a piece of stiff steel wire (at least 20 gauge or so) to go from the bottom of the valve pin to the top of the nib. Double up the wire and cut the ends on a sharp diagonal. Stick it thru the center of the nib, seating it down in the valve. This way the valve is definitely opening every time you push down. Godly drips.(ap reply) I think your just pushing too hard homie.
Hey AP, I got a Krink bleed thru red, and well its empty now, would smash ink go good in it? or is it to thick for the nib or what?( ap reply) Im running silver smash in a a Uni right now. its about the same marker. I added a little (you don\'t need more than a few drops) Garvey to it to give it a purple little halo and extra stain. try that...
