product works great, reasonable price

Reasonably priced set of 5 blue and 5 black Parker style pen refills. Thye work as well as original Parker refills and a price performer level. I like that I had the option of getting a combination of blue and black inks since I didn't have to order a complete ten piece set of each color. I like to use each color at different times.

I'll make this brief, as I tend to get wordy and loose peoples interest (yeah, it's a problem I know ; ) In any event, I've been looking for refills for the many nice, "Parker style" twist pens that I have accumulated over the years. Have you ever been to the local drug store to get a refill for your trusty old favorite pen? (I'm dating myself, but who cares?) In any event, they don't have them or the selection is very limited and specific to pens that they sell. Anyway, after measuring the empty cartridge that I had and matching it up with the photos of these, I decided, what the hell, for $8 bucks or so, I'll try them and keep my fingers crossed. Well, they arrived quickly (I do have Prime) and they fit and work great! In fact, I ended up replacing the cartridges in every "Parker" style pen I had and have rediscovered some old favorites in the process. These are inexpensive and work well. That is, they write smooth and the ink is black (in my case). In any event, do a little basic measuring and comparison of what you have to the photos shown here on Amazon and you should soon receive some great refills for those old Parker style twist pens that have been laying around in your drawers useless, until now! Hope this review helps someone! Cheers!

Use these in a variety of pens and the ink flow is good. These fit perfectly. No issues so far.

These fit my TAC pen perfectly. The included springs are much appreciated as I seem to lose the spring with every cartridge change. Ink flow is excellent with no smudges or skips. I use a pen at work daily and we have to be careful of how we mark off our procedure checklists. We cannot have a pen that skips or smudges (yet the company supplied pens are the worst cheap garbage pens that always smudges and leave glops of ink everywhere lol). Cartridge life is decent enough to make these a better value than some name brand stuff. I have not tried to write upside down with these yet so I can't tell if they are pressurized (for this price I would be shocked if they were). I have had no issues with the tips freezing up and love how smooth these write. No they are not a Pentel energel gel pens but are one of the smoothest writing ballpoint ink pen I have come across. Zero complaints

This cartridge fits certain pins The pin was purchased because it was a good weight these cartridges filled the pins and they write very smoothly as far as longevity The first cartridge that was in the pin lasted quite a few years.

Perfect arrived earlyYes i recommend
