Jaymo Replacement for Parker 30526PP and Bastion - Measures 3.875 in / 98 mm Long - G2 Gel Ballpoint Pen Refill - 12 Blue

Good product! Good quality - quick service!

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.

The refills fit my pen perfectly, and in most situations, the writing is smooth. However, I noticed that on some paper surfaces the pen stops working on some sections of the page.

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.

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.

I have always used the original Parker replacements but decided to give these a try, they work as they should with the exception that every single one I have used in my pen ends up leaking all over after a couple months. I will never deviate from the original again!

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.
