Cartridge for Muji Fountain Pen

[XerQ]

Hi,

 

Acquired a Fountain Pen from Muji with nice greyish black ink. Looked similiar to an international cartridge but to my dismay, my waterman converter/ duke / jinhao convertors didn't work. Neither did the "Muji" cartridge fit my other pens.

 

Sailor didn't seem to work, not sheaffer either...

 

Anyone with any other idea?

 

Thank you!

mine just takes the standard international cartridge, is it the long aluminium pen?

It's the long aluminium pen! Weird... Cross fingers and will try again... Hope it won't leak.

[Beechwood]

Best of luck, standard international cartridge, hold the nib section and push down firmly on the cartridge, should be fine!

It should take an international cartridge or converter. Waterman converters have a slightly larger opening than international ones. Sometimes they fit, sometimes they don't. If you've used your international converters in a pen that fits Waterman, they may become stretched out and no longer work in your international-only pens. I've had that happen to me a couple times. Now I just make sure to have one converter for each pen!

Weird. I have one of the long-barrel Muji aluminum pens, and I bought not one but two international converters, and neither one fits. At all.

 

So now I have two spare converters, and I can't fill the pen back up. And I make a mess when I try to fill a cartridge with a syringe. (Do I need a needle for the syringe?)

(yes)

Apparently, the screw-in international cartridges are what fit. (I had tried only with pop-in/pressure cartridges.) (Anyway, that's what the lady at the pen store put in mine and she assures me that it won't leak.)

I presume you mean "screw-in international converters" -- a number of pens that take international cartridges have screw-in converters, from at least one Hero up to Montblanc C/C fillers. Can't say if they all have the same threads; I've only got one (that I know of).

Yes, that's what I meant. It's not screwed in, however: it's just jammed on, but the one with the threads (monteverde brand) is the one that fit. I filled the pen up last night and it doesn't seem to have leaked, so it does appear to be an appropriate converter for it.

I own a Muji fountain pen(long aluminium) and I use a dupont converter in it. It works fine and it fits. I can also use standard int'l carts in it too.

[encremental]

Muji do (or at least did) produce a pen which takes a tiny proprietary cartridge, which is quite a bit smaller than the standard international. Muji shops here in London sell the cartridges (in little packets of two), but annoyingly not the pens - no fountain pens at all now, sadly.

I know this post is late to the party, but for the benefit of other FPN'ers who might find this...I found a Muji for $15 from HongKong, and it came with one international cartridge.

Having read up on everything Muji here on FPN, I've just bitten the bullet, put some silicone grease around the barrel screws, and yes............. it's now an eyedropper, no 'O' ring needed!

I think the really precise screwfits on the aluminium barrel are the reason for that.

It writes like a dream, and because it's mainly Alu, I have no fear of Lamy Blue Black, and it's inked up and happy.

Hope this helps.

Is it the iron-gall blue black? I'd expect that to eat away at aluminum!

 

BTW, I have a Reform converter in my Muji.

I've heard from a fellow Lamy BB user that it is not iron-gall, and I have a mind to try it.

[Gloucesterman]

Bought a Muji a while back and recall using regular international cartridges. Also used a regular international converter. Because it had a medium nibs I ended up selling it to a friend who has not said anything negative about it.

 

For what it's worth, I have a screw-in converter on my two Viscontis - an Opera and a Kalideo. In fact, I kind of wish that more modern pens had screw-in converters.

[NedC]

Bottles of Lamy Blue Black used to be iron gall, the cartridges never were, but they rationalized their production and now use the non iron gall formula across the line. However, there are still likely a lot of bottles of the ferro-gallic blue black out there in the wild.

 

Never had any problems with cartridges or converters in my Muji, it has a regular Schmidt K5 converter filled with Sailor Sky High in it right now. It's a really handy pen to keep in a notebook because it has a good seal, is rugged, cheap and reliable and is both slender and equipped with a sturdy clip. A rare combination in fountain pens it seems.

I had the same problem. I bought a Muji aluminum pen with some cartridges which were put next to the pens in Times Square. When I finished the cartridge that came with the pen, I tried to fit the Muji cartridges to the pen, but it didn't work. Standard cartridge did work though, so I am using those with my Noodler's ink with a converter from Schmidt.

 

The Muji cartridge says "Cartridge A." I speculate it goes with another type of Muji pen, but the US store somehow got confused and put them together. The last time I've been to that store they stopped selling the cartridges all together. Anyone know what type of pen will go with this kind of cartridge?

Just to jump in on this one, Muji has 2 fountain pens, the one reviewed here and the smaller one (4 inches). The smaller one takes MB cartridges perfect... the MB converter is to long.

 

Both have what I would call a standard EF nib, and they don't have options on nib sizes. Pretty cool pens, but for the price I'd take the Pilot Metropolitan or Lamy Nixx.

[Aurko]

I would say that they have the equivalent of a Medium Fine Japanese nibs? All of my friends seem to agree on that. That's a little bit narrower than Western Fine but also thicker than Western Extra Fine, if I'm correct. The smaller one can take the monteverde mini converter or the Kaweco squeeze converter, but those hold miniscule amounts of ink. I confirmed at the Fountain Pen Hospital that most, if not all, standard international converters work (for the long ones), but the Pelikan ones seem to fit more snugly for whatever reason.
