work well

Used for work but I have been a calligrapher for a very long time and have had hundreds of pens from quill pens to $300 fountain pens. Love rollerball pens and ink. Will not be buying any type of refills on ad Macon from today forward

I can’t comment on how long the ink lasts, but this refill fits in my pen that originally used a Itoya NPR-5 rollerball refill. This generic refill produces a nice thin black line with roughly the same ink flow as the original refill. The price is right. If the ink fails too quickly, I will update, but I’m pleased with my purchase.

Works perfect with yhe pen. Not very smooth though.

You have to get these metal refills for the rollerball pens like Duke and Nekigoen. The plastic Schmidt refills do not fit even though they look like they would (metal tip is bigger). These roller ball pens are hefty and smooth writing. They give the look of a fountain pen without the ink cartridge mess.

They gave a free blue refill which was very nice. However, you get what you pay for. The price is cheap and the refills can get the job done, if you’re on a tight budget and just need at least something to write with. I’m a pen snob and I write a lot so the experience was underwhelming. It is scratchy, not smooth at all, and the ink flow stops every once in while. My hand started cramping after writing half a page, so I will be throwing away this 1st refill and trying another one. Hopefully the others ones are good. I will update my review once I’ve gone through all of them. Update: Only 2 refills was barely passable for me. The other 4 were too scratchy or skips a lot.

Great refill.

Passt in den Schreiber. Alle anderen Minen waren vom Fachhandel zu klein. Leider sind die Maße in Inch. Schreibt aber trotzdem gut.

Good stuff.

Funzionano perfettamente

Estou usando sem nenhum problema.

Great inks, write exveptionally well, fit my pen (custom built one for me) and surprisingly I enjoy using these inks. I have no faults in them, i do suggest and hope you enjoy them as much as i do, keep in mind the fitting of them pre purchase.
