30 Pieces Ink Pen, Ballpoint Pen Refills Replacement Ballpoint Black for Retractable Pens Office College School Supplies (Blue,0.7 mm)

A good value for the price, I got them as replacements for some old pens I didn't want to throw away. Some I had to cut to size to the original shorter sizes, I could not replace just one for a pen that has a slightly larger ink tube. I have been using some of the pens already and they work fine, ink flows ok. All in all I am satisfied.

Excellent value and good quality

Most work well. Good price

These ink pen refill isn't the best

Made for metric sized pens....

I bought these to replace the ink in custom printed pens which I didn't want to throw away when the original ink ran out. I swapped out three pens tonight and the new replacements write perfectly. Two of the pens had originals that were shorter than these, so I simply cut the replacements to the size of the originals. I know replacements sometimes dry out sooner than originals, but with 30, I can swap them out again and again. I'm keeping them in their little case inside a ziplock to try to keep air out until needed. I recommend these!

These refills are horrible. I have an extremely had time getting them to write on any surface. Have taken one out and put in another multiple times. The surface doesn't seem to matter and it's the same with them all. The stead flow of the ink in basically non-existant. It takes forever to get something written.

Bought them for a specific pen, but did not fit, although they fit perfectly with my pentel pens so I kept them; and they are working beautifully.

I have not "dislikes". I have several good ballpoint pens that needed refills and those received do the trick.

تماما كما أردتهم مخزون كثير للقلم وبسعر ممتاز جدا

J'en avais bien besoin sauf que pour mes stylos, ils étaient trop courts. J'ai bricolé un peu pour que ça fonctionne mais il serait bien que pour la vente en paquet de ce genre, on est la possibilité de différentes longueurs afin d'éviter de retourner ou de bricoler. L'encre est parfaite par contre, 10 sur 10.

Another cheap Oriental product , misrepresented to fit the Pilot Better Retractable Pen! Never Again will I believe the Amazon descriptions, I'll shop elsewhere for the items I Need!
