Jaymo Replacement for Parker 30525PP and Bastion - Measures 3.875 in / 98 mm Long - G2 Gel Ballpoint Pen Refill - 6 Black

This is a fantastic pen. I liked it so much I bought one for my brother as a gift.It has a nice weight to it, but not overly heavy. It feels great to write with. It has a smooth finish which I thought was going to be a problem with slipping in my hands, however I was wrong about that.It takes standard Parker refills so you have a lot of options there which is nice. I've used Parker brand as well as cheap knockoffs and they all have worked.My only gripe is the clip which works on shirt pockets but it too narrow to easily attach to pant pockets. This is my daily writer (and I use it a lot) so I carry it with me anywhere I go.For less than $20, this pen is far superior to the Parker Jotters available.

I bought this to replace a generic pen refill that came with two custom-made pens that I bought at the San Francisco Pen Show. The pen looks great but the generic refill wrote awfull - they skipped and the color was not deep. Well these Parker refills fit into the pens perfectly, writes smoothly, with navy blue color. Exactly what I wanted! I've seen ordered some more as backup.

The Jaymo refills aren't bad but to have a couple of drawbacks. First they are made in China not Germany as the product info seems to suggest. Maybe the ink is German but the package clearly states "Made in China". Second, the ink is not as brilliant a blue as the original parker Gel refills. It's more if the blue you'd find in a regular ballpoint pen. But other than that, they aren't bad. The ink glides over the paper pretty smoothly and the flow is as good as the Parker refills. I can't speak about the longevity of the refills as I just got them. But for the price, these refills are good. 3 stars, I took one away for the misleading info about their country of origin, and for their lack brilliance in color. But other than that, it's a solid refill at a dynamite price.

I bought these to replace the Parker refills I previously bought. Very disappointed in the low quality of the Parker brand refills but so far these have been very satisfactory. Long lasting and no skipping.

While form and fit are correct, the function is terrible. Ink does not flow from the blue refills. The black refills work reasonably well, but do not last very long. I'm going back to genuine Parker.

These refills are thinner than what I expected. They leave a fine line the size of .5mm instead of the medium .7mm that was advertised.

All gel inks will smear on glossy surfaces if not allowed to dry. With that said, this model performed better than the Parker brand. Can write on the Ziploc bag white label area. You do have to keep the old spring, as all manufacturers do not provide replacement springs with their refills, even the Parker brand. Very smooth writing, no skips.

Found a beautiful pen in my desk drawer that I had forgotten!! It is a very nice pen, not a cheap Walmart pen, given to me by my employer. The ink had dried up or was used up. So I turned to Amazon to replace the ink cartridge - perfect. Reasonable cost, came with 6 refills. This beautiful pen is back in business!!

Although these fit in the Parker pen and work ok, they are not gel replacements, just simple black roller ball replacements and write no where near as nice as Parker gel cartridges. I won’t be buying these again when I want gel replacements.
