Penneed Ballpoint Pen Refills with Spring for B5/B6/B8 Pen, Parker Waterman Compatible Ballpoint Pen Refills Twist Action Medium Point 1.0mm Pack of 10(Blue Ink)

Good fit - as advertised

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!

Perfectly adequate for what I wanted, arrived safely and as scheduled

Excellent replacement for twist ballpoint pens. Smooth writing ink flow that dries without smudging!!

I ordered black ink but blue ones arrived. It's a really minor thing but it's still annoying. The quality is great and they fit perfectly so I'm using them anyway. Next time I'll just try somewhere else.
