Schneider Ink Cartridge, Standard Format, Ball Closure, Refill for Fountain and Cartridge Rollerball Pens, Black Ink, Box of 6 Cartridges (6601)

I use these cartridges with two BEILUNER Fountain Pens that I have. The cartridges work very well, with smooth flowing ink and good color. I am also impressed with their water resistance. It is far superior to other fountain pen ink cartridges that I have used. Highly recommended!!

Great product

I love these. The ink is easy to install and dries quickly. My only concern is tjay these don't come in large pack. If I could get more than 6 I would ne much happier.

Worked great in my fountain pens.

Este producto es muy bueno para las plumas no se bota la tinta ni te manchas las manos y la caligrafía con buenos resultados.

I bought these to do refills in my Wordsworth and Black fountain pen...I tried 3 and all of them leaked out...Completely. Maybe a good fit in others but not for me

quickest ship ever! product quality is as expected.

Years ago my wife bought me a beautiful fountain pen from day timers, a company that sells journals, etc. they discontinued this pen, and I could no longer get the ink cartridges. I found it some days ago, and got on Amazon. I did have the last empty cartridge to compare- did a search and came across this. The size was perfect- if it didn't fit, I didn't want 20 useless ink cartridges around- those with grandchild will understand. But they fit perfectly, the ink is an excellent shade, and I have a valuable gift from my wife back!
