4.37 inch Rollerball Pen Refills, Roller Ball Fine Point 0.5mm, Black Ink Refill Pack of Replaceable Pen Refills Medium Point (6 Pack)

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.

These 4.37 inch Rollerball Pen Refills offer great value for anyone looking to keep their favorite pens going strong. The 0.5mm fine point delivers smooth, precise writing with every stroke, and the black ink flows consistently without any skipping or blotching.The refills are easy to replace, and the pack provides an excellent quantity for the price, making it cost-effective for those who write a lot or go through refills quickly. The quality is comparable to higher-priced refills, which makes this an even better deal.If you're a fan of rollerball pens and want to stock up on reliable, affordable refills, this pack is a perfect choice.

Refills appeared to be dried out and did not work at all out of the packaging. Total garbage.

good

Nice refills for the Sheaffer pen I have (brand not listed in specs, but measurements seemed right). The rollerballs are not as silky smooth as the original ink cartridge that came with the pen. I usually like medium point rollerballs, because fine point are "scratchy," but these are medium point and still a bit scratchy. No rating on longevity, because I haven't used them for long enough to assess.

I’ve used 3 refills out of the 6 in the pack since I bought these. All of them shared the same issue, the y skipped in writing, you could see from my screenshot on my notes, broken lines, skipped writing. So frustrating.

work well

Unfortunately upon my initial opening and use - the nibs were skritchy, caught the paper fibre, etc., I gave the remainder away...after leaving a crappy review. I picked up my pen this morning, like what two months+ later and that pen is smooth and the ink flows wonderfully. and now I'm thinking DARN, I gotta re-order!So - humidity in general is a thing and they probably dry out in transit, just let the open nib/s sit open after lightly getting the ink to flow. Use a very light touch at first - this explains the unpleasant reviews! These pen refills are worth the price - a good value - don't know how long they will last yet...

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.

El recambio original no se encuentra. y éste por la medida es el que mejor encaja, teniendo en cuenta que es fija su posición sin muelle. la tinta no está mal pero prefiero la original, porque se desliza diferente.
