OHTO Flash Dry Gel Ballpoint Pen Refill 0.5mm [Black] PG-105NP 3set (Japan Import) (3 Refills)

Fits the zebra f-701 metal pen. Great to finally find a gel cartridge that fits such a robust pen.

writes quite nicely but not as good as the .7mm ones but good enough. had it for a couple of weeks now and no signs of drying yet.

I bought the pen to this cartridge out of a stationary, and had no idea what I was buying. When I got the pen home, the ink was too light and ballpoint. I hated it, but paid too much for the one to throw it away. Luckily, I found a gel cartridge on Amazon and now I love this pen! I would absolutely recommend.

Great refill for the most part. Dark ink, dries FAST, smooth writing, indelible (not advertised as indelible ink but it's up there with Uni's ink), etc. My only complaint is that sometimes it has flow issues, especially when writing on surfaces that aren't horizontal. Also struggles to put clean lines on any mildly contaminated surfaces which seems to exacerbate the flow problem. But 90% of the time it's a great refill with smooth, fine, dark lines that dry quickly. You just might have to scribble in the corner every now and again to get it going properly.

Solid construction, good ink flow/dry speed, and fit my Zebra F-701 by removing the plug opposite of the tip.

I bought this refill because I read that it works with the Zebra F-701 without any modifications. That's true, but it's not a 100% perfect fit right out of the box. The tip of this refill is just *slightly* too big to fit through the plastic insert in the tip of the F-701 smoothly. It does fit, but there's a bit of friction and it makes the click a little less satisfying at first.I tried removing the plastic insert, but that made the tip a little too loose and wobbly for my taste. I ended up using a small drill bit to stretch/ream out the tip of the insert (by hand) and that did enough to make me happy. I'm sure it will get even smoother as it breaks in over time.As far as the refill itself goes, it writes smoothly and makes a fine dark black line. The ink dries very fast as advertised, and I'm not sure I could smudge it if I tried.

• Pilot “G2” is not the same as the “G2” pens that we all love.• Pentel “G2” Gel clicky top pens = awesome rollerball.• Pilot “G2” is a ballpoint = not my favorite, isn’t gel.• Parker Style is a form factor for ink refills that is completely different from the ones in the Pentel “G2”.• People confuse those three terms. I don’t know why Pentel named their fantastic gel pens “G2”.• This refill, Ohto Flash Dry Gel Ballpoint, writes like the Pentel “G2”; aka like a gel pen.• This refill is “Parker Style”.• Get this refill if you are looking for a refill to make your “Parker Style” pen write like a “Pentel G2”.• The above picture is of my rOtring Rapid Pro and a Tül clicky top gel rollerball; both are .5mm.• The rOtring uses a “Parker Style” refill; the Tül a “Pentel G2” refill.• The Ohto Flash Dry Gel Ballpoint refill fits the rOtring, and writes like a dream.

If anyone is wondering. These do fit in the Refyne EP1 edc pens. Which was the specific reason I purchased this item. Writes smooth right out the packaging as well. Definitely recommend.
