Jinhao Fountain Pen Blue Ink Cartridge International Standard 2.6mm Bore Diameter Ink Refill Set of 30 PCS

Fits smaller bore. Good ink at a good price.

I bought these ink cartridges because they were said to fit in the Amazon Basics fountain pen, which was my first fountain pen. I am still new to inks and pens but I can tell you that these Jinhao ink cartridges do work for that pen pretty well, and are a lot longer than the cartridges that came with the Amazon Basics pen. I use that pen for everyday writing, and I know that I will still be using these cartridges for probably over a year before needing to order more. I will note that they are too long for the Speedball fountain pen I picked up at a local art supply store, but I don't like that pen as much anyway. I am now waiting for a Jinhao pen to arrive and enjoying these cartridges. Pictured is the Amazon Basics ink cartridge (that I use in my Speedball now) compared to one of these Jinhao cartridges with a dollar bill for reference. The other picture also shows the cartridge currently in my Amazon Basics pen that I have used about quite a bit of compared to the dollar bill and another Jinhao cartridge completely full and on its own. I hope to switch to bottled ink when I finish with these to waste less plastic and have more color variety but I will likely use the Jinhao cartridges day-to-day when I return to working in an office and want the added convenience. I like that there is a blue option for the ink.

I'm pretty new to fountain pens, but here are my thoughts: The colors are OK, but a bit weak in some cases. I couldn't get a good fit on one of my pens, and I think that caused a lot of skipping. I think it might just be that pen though. I tried most of these inks in Jinhao 599s. So, not great pens, but hey, this is cheap ink. The Orange and Violet-Blue are my favorite of the bunch. The Orange is bold enough. It's an "Irish Flag" color orange, and The green next to it really invokes that ( at least in March). The Green is OK, but I have had such a hard time getting it to flow well. Apple green is a good description of the color. Maybe a bit less "acidic" looking than that. I really think this comes down to my pens, so maybe I'll try it in a pen that I know writes well with a cartridge and reevaluate it. The Violet is really nice. I think it's dark enough to not look too delicate for my taste. I think it's "Kool-Aid Grape" Purple. It's fun to write with. The black and blue are ok. pretty standard, in my opinion. The red is weak looking. It's almost pink. Maybe slightly orange, but definitely not in the salmon range.

Quick delivery and great quality

I bought these cartridges for my Jinhao 82 fountain pen and they are perfect. great flow, ink takes very little time to dry on paper. I ordered the black cartridges but may end up ordering the color pack as well! tons of ink, should last me a while. Would definitely buy again for my Jinhao 82. Oh- I will note when installing, you will need to put pressure until cart clicks into place!

It’s ink ! It is very smooth and drys fast . I think you will be happy with this ink !

These ink cartridges do not fit in the Jinhao 10 or 20 and apparently they are not returnable. Very disappointed. Can’t see any reason they can’t be returned. Amazon paired these cartridges with the Jinhao 10 and 20 pens which in my opinion suggests they are compatible. I returned both ink pens and ordered a different brand of ink pens.

Nice price good size but the ink colors are not very strong. I was hoping for something a bit more vibrant.

Todo muy bien, cumplen su función, llegaron en el tiempo prometido

These are a little narrow for some of the bigger brands of fountain pens (ie Lamy) but they're lovely for the Asian brands that I have and fit my J Herbin brand rollerball pen (https://www.amazon.ca/gp/product/B00A6VZYKE/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1), which as a side note is a nice pen option to have and I would suggest it for any ink lovers. These do not fit Schneider brand rollerball pens (ie: https://www.amazon.ca/gp/product/B07MPHQXVP/ref=ppx_yo_dt_b_asin_title_o02_s02?ie=UTF8&psc=1)

When firmly inserted in the pens of the same brand, all the pens leaked out the nibs. Caps filled with ink and when you took the cap off you had ink everywhere

万年筆をよく使いますので、二回目の購入をしました。綺麗な黒色です。インクの流れも良く、スムーズです。コストパフォーマンス抜群です。

コンバーターが不良だった（新しいコンバーターも二個送って頂きました）ので、購入しました。色は、ペリカンのロイヤルブルーより若干濃い色合いです。パイロットのブルーブラックの青色を強くしたような色です。初めて使いますが、私は気に入りました。
