Zebra G-301 Stainless Steel Pen JK-Refill, Medium Point, 0.7mm, Black Ink, 2-Count (6 Pack)

Firstly, I don't use these to refill the G-301 pen, but instead I modify them to fit into the much nicer F-701. You need to do four things: 1) cut the G-301 down to the length of an F-301 refill. 2) Take the black plastic plug from an F-301 and put it into the G-301. 3) Remove the clear plastic cone from inside the tip of the F-701. 4) Use the spring from the F-301 and reassemble the F-701. You now have one of the most popular and affordable EDC pens with the smooth writing of Zebra gel ink.As far as the refills themselves go, they are small but they do write very smoothly. I would compare it to a Pilot G2 0.7mm. I have yet to see one skip. The line goes down pretty wet, and you can even watch the ink soak into the page after you write a word. I'm left handed and it doesn't bother me at all. It never smudges from my hand, but it does smear a bit after using some highlighters. The refills biggest downfall is the size compared to other gel refills on the market. From just taking down quick notes at work and to-do list type of stuff, they seem to last less than two weeks. But to me, it's worth it because of the F-701. I compare it to driving a nicer vehicle, but with less gas mileage. It's not for everybody, but I can make the sacrifice.I wouldn't recommend this to someone who is writing pages at a time, but if you need something to carry with you for note taking, these work nicely in the G-301 and even better in the F-701.

Great Quality. Great price

My co worker needed these for his owns. Great refills. The ink is great, color comes out great, the function of the pen is great, and they feel great.

Despite some minor smearing with highlighters, these refills stand out for their high quality. They may be smaller than other gel refills, but they last less than two weeks with regular use for notes and to-do lists. The F-701 pen makes it all worth it, like driving a luxury car with slightly lower mileage. While not suitable for everyone, I find the trade-off well worth it.

Favorite pen. Only complaint is that it runs out of ink quickly. Otherwise they write smooth and feel great to use.

Great value on this item
