Sailor Jentle Black Ink Cartridge

Thank You.

I love the color flow and the fact that I can use these cartridges in my Wing Sung 628 fountain pen.

Bought these cartridges to go in a vintage Sailor pocket style pen and they work great. The ink is high quality, flows well, and produces a medium-dark black line on the paper. Dry time is about average compared to my other fountain pen inks (mostly Diamine, Robert Oster, and Iroshizuku).

The perfect black ink. it's dark and consistent. My favorite black ink.

I recently began using a Sailor fountain pen that was a gift from my mother-in-law back in the early 1980's. The pen is beautiful and feels wonderful in the hand, but I was never able to use it because I did not know where to find ink cartridges for it. Fast forward to today and finding the cartridges on the internet was easy. They were shipped quickly and I was finally able to use this pen for the first time. I have used other fountain pens, some wrote well enough while others weren't worth the effort. If you like using a fountain pen, the Jentle Ink from Sailor combined with the beautiful pen they produced are a wonderful experience. I am also using the same ink in bulk form, refilling the cartridges and the quality is the same in both bulk and cartridge form...high. If you have a Sailor brand fountain pen, these cartridges are a fine choice to write with.

Wish it was waterproof.

Fine product delivered punctually!!!

Clear black ink, feeds very well. Can tend to bleed in Moleskines and other such paper.I notice if I've had these cartridges around for a few months that ink seems to evaporate from them at a quicker rate than with other companies' cartridges. I haven't noticed that it makes the ink any thicker or affects the pen, but whether evaporating or sublimating, up to a quarter of the ink is gone a few months out.I have a Sailor ProGear pen: 21K nib. Writes so smoothly you might hurt your wrist zipping off the page. This is the ink for it, unless you go for the more permanent (mostly waterproof) Kiwa-Guro ink.
