Kaco G2 Gel Ink Refills for Retractable Gel Pens, Fine Point(0.5mm), Pack of 10 (Black)

Works great and a good value for the cost.

The media could not be loaded. Love these refills, they fit my pens perfectly. Never given me any problems and I love that I can keep using my favorite pens. Ink is great and I've never had any leakage.

I was pleased to find a replacement gel for a very special pen given to me as a gift.Interestingly, the paperwork that came with the pen gave me information for replacement with Amazon. Otherwise I would not have known how to purchase the "refill" that came on the pen initially.My penmanship is smooth and neat on letters, cards, checks and so forth. The replacement package contains multiple refills. Very satisfied.

The perfect refill for my Rifle Paper Co pens

Overall, they're not a bad refill. The line width is nice, but a couple of the cartridges I had to throw away because they skipped too bad while writing. The rest work fine so it's definitely worth the money given how inexpensive there.

I have tiny handwriting, so I normally use very fine point gel or hybrid ink pens, especially when writing in my journals with 6 mm line spacing or my Day-Timer work diary with a tiny 3.5 mm line spacing. These Kaco 0.5 mm point G2 Gel Ink Refills are the best option I have found for installing a sufficiently Fine point refill into my collection of nice ballpoint pens that take Parker G2 size refills. Note that by typical USA standards, these refills have a Very Fine point, producing a line about the same width as a line from a Uni-ball Signo 207 0.5 mm Micro point gel pen or a Pilot Acroball 0.7 mm Fine point hybrid ink pen, which are both significantly finer than a line from a "Fine" ballpoint refill from Parker, Sheaffer, or Schmidt. These Kaco gel refills also produce a little more feedback from the page than a Uni-ball Signo gel pen or a rollerball; someone who rarely uses very fine point refills might call these "scratchy." If you prefer a bolder, free-flowing writing experience like you get from a liquid ink rollerball pen or a bold ballpoint refill like the Schmidt EasyFlow 9000, then you won't like these refills. But if you are looking for a Very Fine point in a Parker G2 size refill, then these Kaco 0.5 mm point gel refills are your answer. I even modify them to work in my pens that take Sheaffer K refills by using an X-Acto knife to trim the plug in the back of the Kaco refill to length, followed by sandpaper or a small file to reduce the top diameter of the plug to match a Sheaffer K refill. I have already ordered these twice, and if they are still available when I need more, I will probably order again.

I tried these as an alternative to my preferred gel refills for my Rotring 600. Despite reading other customer reviews that mentioned their inconsistent inkflow, I decided to give them a chance since the price seemed so reasonable. Well, despite being only marginally cheaper than my preferred refills, these Kaco refills are absolutely NOT worth their price. The inconsistency is beyond any other cheap refill I have tried. 9 times out of 10 I had to retrace letters, and certain letters with long vertical strokes would not print AT ALL until the third or fourth try. Writing with these refills made my handwriting look like that of a child. I thought that perhaps I had started with a faulty refill, but the problem persisted with each refill in the pack. I ended up throwing them away. I would advise saving your money unless you have the patience to spend half of your time retracing letters. It's as if these refills demand that you sit and teach them how to work, and yet they refuse to learn. I've never had a less reciprocal relationship with a pen refill.

I have two pens that use this "Parker style" refill and I got these for them. Ive gone through 4 refills out of the ten trying to find one that doesn't skip. Its been very frustrating. The lines are very fine and dark which really helps my small handwriting but they are too scratchy. Someone else mentioned dragging a straight pin across paper and that's a good analogy. I'm going to try the rest of the package before I fully make verdict but it's not looking good. I'll update this review then.
