UniBall Signo Bit 0.18mm Pens


World's thinnest line pen

World’s thinnest ballpoint pen…thinnest possible lines you could ever write. It’s quite fine. It has some sort of special ink for reducing friction so it won’t clog. It’s not super-flowy like a normal gel pen but it allows you to make sharp and precise short lines, which is what I suspect it was designed to do (i.e. for writing Japanese characters (see circle in picture with writing between lines of text), or alternatively adding fine details into drawings). I think it’s pretty cool.
