These are expensive and you have to get used to the steel ball tip. You can't apply too much pressure or almost nothing comes out. I say pick one up then switch out the tip if you want on your other K60s instead of buying more of these. I bought one of these in gold and didn't like the steel tip with it so I just put a K60 nib on it and put the K66 nib on an ART Primo mop which I will fill with smash ink.
had this marker for a lil over a year now, still works :D i used it to make stickers and used it in blackbooks for my peices , overall , one of the dopest silver markers ive had :) n its not really meant for tagging but its still works for catching a tiny spot :)
I tryed in the rain didn't work but still amazing on poles, concret, boards, and mailboxes. But wish th really were water working(apreply) if you want something that writes on anything then get a Hobo Marker.
