At first, I thought this was just a dumb gimmicky feature, but then I found myself using it. The pen’s namesake feature is a clip at the end of the pen. And if you’re not as impressed as I am by that, use more pens. Literally line upon line of notes in black ink and once you turn the page you can barely even tell. I was utterly shocked and delighted that (despite the aforementioned light smearing) these pens not only didn’t bleed through, they barely even shadow through to the next page. In the past three weeks that I’ve used this pen in my planner, there’s exactly one smeared line of scribbled notes. This isn’t usually a problem for me because I don’t drag my hand much when I write. Lefties beware: They also delivered the smearing that you’d expect from a gel rollerball. Basically, they’re a set of pens that write like…well, pens. These pens don’t quite float across the page like some gel pens (*cough* my beloved uni ball signo *cough*) do, but they still don’t scratch or skip. This is important, because a gel rollerball that doesn’t write smooth, clear lines finds its way onto someone else’s desk, or the trash depending on my mood. They’re a gel rollerball pen, which means I went into this expecting smooth, clear writing from these babies.
