Itoya Aquaroller Pen Refill, 0.7mm, Pack of 2, Black Ink (AQR-7BPBK)

Fits the pen I purchased them for and has a nice fine smooth glide when writing. Enjoyable to use.

Using these in my EDC pen. Typically, I want ink that is dark and doesn't smudge. This ink fits the bill. These are Parker-type refills and they write very smoothly on a number of surfaces. Generally I'm using them with Field Notes books, whose paper has a very nice weight. No bleed-through at all. On regular paper (such as copy paper), the darkness of the ink will let it be seen a little on the back side, but still no bleed-through.This ink is very black and dries quickly without smudging; on Field Notes' waterproof Expedition paper, though, it takes a little longer to dry.Overall an excellent ink for everyday use.

To start with, my absolute favorite pen is the Pilot V5, extra fine. But it's difficult to find a metal barrel that holds it. Enter the Itoya Aquaroller! No, this is not as good, but it is certainly close. Not as fine a tip, but it's finer than .7 mm would suggest. Basically, it writes wonderfully fine. It's also a roller ball, not a gel type like the V5, so not quite as dark, and almost, but not entirely as smooth. But, and this is my favorite part, it fits perfectly in the Parker and my other Parker style edc pens! I really love this cartridge, it will be the only refill I use from now on.

I have a lot of pens that take Parker-style refills and there aren't a ton of gel options. The ones that are available (short of the Monteverde Ceramic Gel) are thick and just don't suit me all that well... These Itoyas give me nearly the same experience as my preferred gel refill — the Pentel Energel 0.5 — but they work with my smaller retractable pens from Maxmadco and Tactile Turn.These work beautifully with a dark, rich line that doesn't skip or hiccup at all. Really, really love these.If you're a gel pen user and need a good ballpoint replacement for your favorite Parker G2-compatible pen, check these babies out!

I love my pen so when I was able to find a refill I was thrilled.

I usually use Pilot Gel refills, which works best for me. The ink is very light and doesn't flow easily. Will be looking for another brand soon.

Fits any pen that takes a "Parker style" refill. Clear body makes easier to see amount of ink. Fine point is good where need to be "precise" in writing, probably great for forms, though still need to be careful, as might smear, compared to regular ballpoint refills, otherwise, nice. Will work, with modification (on two of them) for an older Itoya pen, only one that will fit, forgot to keep the original refill, need to shorten to make retractable, other will use for others, without modification, for any pen taking a Parker refill.

These are smooth writing
