30 PCS Jinhao Fountain Pen Ink Cartridges Refill 6 Colors Set, Black, Blue, Apple Green, Purple, Red and Orange International Standard Size 2.6mm Bore Diameter

Been following a Reddit Fountain Pen page and this pen was repeatedly mentioned as attractive, good quality EDP for fountain fans, also an excellent value for the quality. I do have some other substantially more expensive Fountain Pens, so was delighted with the feel of the pen, the quality of the FINE NIB...It is a good buy

Very nice collection of inks at a good price.

This ink cartridge works okay in some pens, but not the Beiluner. If it works in your pen, great, but it will not work with this pen. The body of the cartridge is slightly too thick to fit into the pen, so you cannot screw it all the way in. Photos show me trying to make it work, as well as a comparison of the cartridge that came with the pen. I give the product 4 stars since the ink is good, but I'm disappointed it does not fit my favorite pen. https://www.amazon.com/gp/product/B07RSZRTX4/

great variety will be giving colors w pen to match as gifts this year

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.

The ink is wonderful! No skipping, no bleed. I will buy this again and again!

Horrible it came in two cartridges was busted open

I gave it 3 stars because, for the price, it is a good deal if you're looking at quantity. If you're looking for quality, use the converter that comes with the Jinhao pen with quality ink. The cartridges, while they work fine, the ink does not apply uniformly and tends to bleed.

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

They work well and it is fun to write in different colours

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。
