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

Love the quality and vibrancy of the ink. It’s not a “mixed” purple. It is what it says it is. Nice and dark and decadent. So grateful for the many packs that it came with. Should be good for a long time.

Fits smaller bore. Good ink at a good price.

Great value ink. Didn’t fit my jinhau 500 but I might have ordered the wrong product. I ended up chopping them open for the ink and using the 500’s converter. Ink dries quickly and looks presentable. It’s a very light color that appears low quality to me, but that could be a preference thing. It writes well and with a F nib doesn’t bleed or feather on my crummy computer paper. I think this is a good starter ink until you upgrade.

I was not thinking that I was supposed to clean the nib if I was changing the ink color from violet to orange. I thought ink cartridge was filled with wrong color when it was spitting out brownish color. It was mixed with previous ink color used. Ink cartridge works really well. Please make sure to clean before changing the color.

My kids like the variety of colors and they fit on the fountain pens well!

Amazing value for money. Compatible with a variety of my pens that use the standard international short cartridge. The ink consistency is on point and I haven't faced any issues. The cartridges seem to be made out of decent material and do not seem to be prone to any leaks. Definitely recommended!

Really low quality cartridges. These do not fit very well into the Amazon basic fountain pen. Given the low quality the cartridges come out and leak. do not buy.

The blue ink in this set of inks is very good quality, maybe as nice as Waterman Serenity Blue (except Waterman bottled ink comes with the bonus of excellent bottles, almost worth the price of a Waterman bottle of ink even without the ink). A couple others are pretty good as well. Black is pretty serviceable, though I'd take Waterman Intense Black or (especially) Aurora Black instead any day of the week. The green and orange inks, on the other hand, seem anemic on paper, and they rob the fountain pen writing experience of some of its smoothness. They feel "dry" and rough, and can probably just be thrown away without really missing anything. Of the inks in this set, I'd only bother buying the black (which you can get in cartridges without any other colors for dirt cheap as well) to give away to people who need some emergency ink or something like that, or the blue if I could get it without the rest of the colors because the Jinhao blue ink is quite nice and it's dirt cheap for cartridge ink. In practice, I might buy more black to give away, as I mentioned above, but I'm likely to just buy Waterman Serenity Blue for my blue ink, and use Aurora Black (my overall favorite ink so far) in my everyday writer. Given the cheap price for this, the "value for money" should be five stars, but the fact a third of the ink I got is borderline unusable suggests I should remove one star from the value rating for these inks. Because of that, a "quality" rating should be lower than the "value for money", "presentation", and "easy to use" ratings I gave this ink, but Amazon doesn't at this time offer a "quality" rating category. It's reflected in my three-star overall rating.

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。
