I have a Yiren 566 and it is leaking ink. If left nib downwards for any length of time there is ink in the cap. Are any of the other Lamy clones affected in the same way?

This is the third Yiren 566 and all three have had the same issue.

The pen is inked with Hero 234 Carbon Black using it's own converter. This ink is somewhat thicker than normal. In the past I have lost a converter of Herbin Lie de The and a Parker cartridge.

There has to be air getting in for there to be the slow flow of ink out or else there'd be a vacuum which would stop it.

On the present pen I have not tried a Parker cartridge that had ink in, but I do have a converter for my Parker Reflex. That felt somewhat loose, I was therefore unwilling to sacrifice a filled cartridge for research purposes.


What would you do?

Strip the pen & re-assemble with some sort of sealant?


I thought the Yiren 566 was a reasonable Safari knock-off.

I have not encountered that problem with the several 566s I have nor any of the many other Safari clones I have. A slow but cheap approach would be to get different converters and/or Hero 359 cartridges from China to see how those work. I think most of the Chinese pens with big bore converters were designed for the 359 cartridges. Some work and some leak with Parker cartridges which are close but not the same, though in my case the ink leaked into the barrely. Lamy cartridges tend to be a better fit leak-wise but are more likely to not fit in the barrel.


Are the converters pushed all the way in? Some Chinese pens require considerable force. Unfortunately they are also prone to break -- not a happy combination;-(

I tried a empty Lamy Cartridge & it didn't seem to fit. I haven't tried the Hero 359 cartridges.

I have made sure there was no air in the Yiren's converter.

I am leaving it laid horizontal & then I will leave it nib-down again while I go off to work.

I washed the cap out, so any further leaking will be easy to spot.

The converter is pushed all the way in.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
