I officially dislike the Sharpie S-Gel, which has managed to get ink on two pairs of pants on consecutive days, and on my notebook holder. And while it has a nice bold line, it's very fussy about paper and angle. Getting ink where it's not supposed to be is apparently not just a #fountainpen problem.
(But if you like the S-Gel, I'm still happy to sell you some.)
@tallastro It has just somehow left dots on my pockets and Lochby. So it either leaks from the tip or maybe gets partially unretracted. Doesn't happen with G2 or any other click pen.
