10 PCS Fountain Pen Short Converters Universal International Standard Size 2.6mm bore diameter

The barrel is kinda small / short so it doesn't hold that much ink, but operation is easy. It only fit my Manuscript pen (right) but not Sheaffer (left) or the inexpensive pen in the middle. I honestly don't know that I need ten of them but this is one of the cheapest one on here with good reviews. Works well. Still have to find other pump cartridges for the other two pens.

I do not claim these are high quality ink converters, nor do I claim they are maid of great material. But they ended an almost 20 year search for the right converter for some of my pens, and they are cheap.When I got into grad school, precisely 20 years ago, we were two broke young newlyweds, but my wife knew I kinda liked nice looking pens and wanted to give me some. She bought me a set from JML with six writing instruments, including a fountain pen. They looked amazing, and were of a nice quality for the price (I know the same set retails now for about $25, so, in that ball park). They have a sentimental value to me. Also, I have a set of calligraphy fountain pens (also on the cheap side) that were also a gift by a good friend also about twenty years ago.The problem with these pens is that although they take standard international short cartridges (they would not take long cartridges), they would not take most converters. Through the years, I had purchased maybe three dozen sets of cartridges from different manufacturers, most of them universal, but a few proprietary, just in case. I have more cheap converters in a drawer than you probably have ever seen.Well, I received these a few weeks ago, I tried them, and wow, they fit both in my beloved JML fountain pen (yes, it is cheap and writes barely OK, but you know, it has meaning to me), and in my caligraphy set.Also, although I just needed 7 and the set said it came with 10, I actually got 11. I have four replacements, and if needed, I know which to buy again.

It works well with the Aihao fountain pen 🖋.

The converters were very small; if you want converters as back-up or for pocket pens, these should be fine.

I can confirm these fit my Aihao fountain pens, https://a.co/d/g0idGmSThey have however extremely small capacity. Will update if they leak after some use.

The quality and value for the price is good. They hold same amount of ink as original converters.

International short refill cartridges are 1.5:, these are 2.24". They will not fit the pen.I informed the seller that they didn't fit, they sent a refill, but then sent ten more.

Buy them
