Ackerman Junior Pump Pen Review

Recommended Posts

I wanted to be able to practise Copperplate without having a bottle of ink and dip pen out, mostly due to having young children who are fascinated by the ink and pen, and always manage to find them if they're not locked away! *The ink and pens, not the children!

I decided to try out a couple of Ackerman pump pens, and compare them to the Desiderata Daedalus. My aim is to have an easier, less risky way of practising. Apologies again for the photos quality, handwriting, and verbosity in this review.

Ackerman Junior Hunt 101 & Gillot 303 AU$17.29 each

Postage AU$2.67 each

3 weeks to arrive in Australia

15 g with a tiny bit of ink inside and lid on.

Lid 4 g.

These pens arrived in a standard C5 (or similar USA size) envelope with a printed invoice or packing slip, and in a squished, flimsy white cardboard box with "Ackerman Pens" on it. I won't keep or reuse the box. Due to the cheap price, I don't expect any more fancy packaging, though being wrapped in a layer of bubble wrap or similar would offer more protection than the box. That's not to say that nicer presentation wouldn't be appreciated. Once again it would have been nice for at least one page of instructions or a welcome note or something to be included.

This pen has a different appearance than is shown on the website. It is plain black (no red stopper) and has no clip on the lid. It is a plain matt black cylinder, darker than the Daedalus and perhaps more consistent in appearance, though not as smooth to the touch. There is an oval hole where the yellow rubber tube shows, and can be "pumped". There is an orange O-ring on the pen body to hold the lid secure. The lid pushes on and is held secure by the O-ring. There is a thinner section inside the lid to prevent it being pushed down too far (fine with Hunt 101 but could possibly still hit the end of a longer nib). The lid posts, although it's a bit loose, but, as with the Daedalus, this makes the pen a bit heavy for me.



The feed is pointy and goes almost to within a few mm of the end of the nib. It has quite a high profile, which looks strange hanging down under the nib, but doesn't seem to get in the way. The feed has a hole in the back of it, then a hole in the top (presumably they connect) then a slit that stops just before the end. The Hunt 101 feed is the one designed for the "Principality" nibs according to the Ackerman website (Manga G, Hunt 99, Hunt 101, Esterbrook 375, Falcon, Brause B, Brause C), and as such is slightly too long for the Hunt 101, so to compensate the nib is slid slightly forward. I found the fit a little bit loose - the nib slides back a bit with too much pressure on the tip. Although this shouldn't happen in normal writing situations, I got so frustrated with the lack of ink flow that I tapped the tip of the nib on the paper (not too hard!) and this made it slide back too far.



I like both the Hunt 101 and Gillott 303 nibs. They don't require too much pressure to spread the tynes, although they are more likely to catch on the paper than the G nibs, and don't bounce back to a point quite so enthusiastically (even if their point is finer).

Filling is fiddly. One of my pens came with an end stopper that was fairly easy to remove, the other one has an O-ring on the stopper which makes it really hard to remove. There is a rubber tube inside the pen body which needs to be filled by eye-dropper.


I have only tested these pens with Higgins Enternal. I don't have any eye-droppers, and couldn't find the one pipette I own, so used a soy sauce fish instead and tried to introduce the ink one drop at a time (didn't work very well - surface tension meant it was inclined to block off the end of the tube) or by inserting the nozzle of the fish into the tube (didn't work very well as it sealed the end, making it difficult to displace air to allow the ink to squirt in). With one of the pens, when I finally did get 5 or 6 drops of ink into the tube, it suddenly all poured out the nib. With the other, sometimes each drop would drip out. With a bit of mucking around (including pushing the nibs and feeds further in), and a lot of mess including ink getting in between the tubing and the pen body and now leaking out through the oval pump hole), I finally got enough ink into the pens to do some writing. I feel worried about ink leaking out of the end where the stopper is, although this may be unfounded.

I found that the nibs ran dry and railroaded fairly quickly. Pumping by itself did nothing, possibly due to the small volume of ink, except when it made sudden big blobs of ink. Giving the pen a flick to get some ink to move down, loosening or removing the stopper, plus a gentle pump, seemed to get some ink flowing. I found myself wanting to dip the pen so I could keep going, which really defeats the purpose. The pen spontaneously dripped ink on one occasion, whilst doing a down stroke, blotting the page badly.

These pens look nice and I had no hesitation buying them to try out (not least of all because one pen plus postage costs the same as postage alone on the Daedalus). I had read reports online of problems with customer service and delivery delays, but decided for the relatively cheap price I was happy to risk it. Then pens arrived (I'm in Australia) 22 days after I ordered them. I am completely happy with that.

I am disappointed with the performance, the fiddliness, and the mess. I can't work out why they don't work better, even just with gravity feed, and I will try them out with some other inks and a better eye-dropper/pipette. The pens look nice and would be a lovely tool if they actually worked.





I decided to carefully inspect the Ackerman pens. One of the pens had a patent barrel. I could see straight through the tube to the other end. The other pen I couldn't see through. I pulled it apart and discovered a white plastic grommet sitting sideways inside the tube. I pulled them out and then tried to reinsert them. This was so difficult, even with the help of a lot of detergent and water to lubricate. I managed to pierce a hole in the tube while using a cotton bud or chop stick or skewer to try to poke it back in. The tubes are made of Thera-Band, which luckily I have some of to replace it with, but I couldn't find any yellow tubing around the house. I used red, which has a minutely larger diameter, but I managed to get it back in and position the grommet at the end of the tube near the section/feed (which I assume is where it's meant to be). I have not disassembled the other pen to see if it also contains a grommet in that position.


I inserted the feed and Hunt 101 nib, and filled the pen with Winsor & Newton Blue Black ink (the blue lid bottle, not red) using a small syringe. The ink dripped straight out, so I tried holding the pen almost horizontal, squirting some ink in, and putting the stopper on quickly. The dripping ceased as soon as I got the stopper on, and there seemed to be some ink still in the pen.

I wrote a couple of lines quite successfully after cleaning the nib up a bit. I then had to put the lid on and go off to do something. When I came back to it a couple of hours later there was ink in the lid and all over the nib. I got it writing again after dipping in water.

The next time I needed to fill the pen I removed the nib and feed, and filled it from the front end with the stopper in place so the ink didn't run out. This was still a bit messy, but seemed to work better. I had to dip the pen in water again to get it writing. Before dipping it in water, if I pumped the pen I could see the ink seeping through the vent, but it didn't make its way to the tip. I think some ink must have dried out between the nib and the feed, and dipping it into water resolved this.

The next two times I went to used the pen, when I took the lid off I was faced with a lot of spilt ink inside the lid, and on the nib, feed and pen body that inserts into the lid. This is very messy and so I think the Ackerman pens need to be cleaned and emptied between writing sessions.


Non-dip flex pen (when the ink flows)

Easy to remove and clean or change nibs.


Nice plain design

Cheap enough that I don't mind playing roughly with it (piercing tube!)



Leaks when trying to fill

Leaks ink into its lid

Messy to fill

Ink flow is inconsistent

Blots spontaneously

Not portable

Thank you for a very insightful review with the images and your comments.


Always found this pen maker and products to be of great interest. However, between the long delay in receiving the pen after ordering, the questionable quality of the product received and the unresponsiveness of the "maker". I really wonder why this person keeps running the business this way.


After saying all of that, I will admit that all I know about this vendor has been gleaned from comments and reviews here on FPN.


Ordinarily I would be very interested in buying and using one these pens but not really ready for that much adventure.

Thanks for the review -- I think these are some of the best photos of an Ackerman that I've seen. It's quite a crude design. To avoid (some of) the dripping, might it be better to leave the end cap in place, remove the nib and feed, and fill the pen from that end instead?

I posted this in a former post, however this seems more current. But, I was just recently contemplating this pen, out of the sheer fact I wanted a pen that can take india ink (for the spite of it)... I noticed that they all come with different nibs, which I am not familiar with. Do you have any suggestions for everyday not taking, and an occasional dabble of flex calligraphy? Do you think the manga g will be good or otherwise? Also in light of your review, do you suggest the senior (the larger versus this junior smaller one)?

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.

      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.

      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to
    • Daneaxe
      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
