Three very different piston fillers

Piston fillers, or piston filled fountain pens, have something of a status in the pen community. There is absolutely something to be said for a fountain pen that comes with its own integrated ink filling system. A piston filler is not as finicky as a vac filler and is considered a step up from cartridge/converter filled fountain pen. In this post I will look into three very different piston fillers: an entry level pen, a design icon and a classic beauty.

As with most fountain pen users, my first fountain pens were all cartridge filled. During secondary school in the eighties, I discovered the delight of the converter and started hoarding those to fill my pens with inks from pots instead of cartridges. Since then, my pen family has grown quite a bit and I have used piston filled fountain pens in different formats for some time. I am certainly not a piston filler expert, but I am very happy to share with you some thoughts on three different piston fillers.

First I have done a very basic “what’s what” for a piston filler, demonstrated by my lovely assistant Aurora below.

Parts of a piston filler

As a matter of fact, the innards of the piston filler consist of more parts than described above, but since this is just an introduction and not a “how to dissect your piston” blogpost (and because each brand will have a slightly different piston mechanism) I have limited the above picture to the most basic parts. The piston filler is operated by turning the blind cap or piston knob, which will push down the piston seal towards the nib unit. Holding the nib unit in the ink bottle and twisting the blind cap or piston knob back towards the body, will result in the ink being drawn into the body.

Cleaning the piston filler is done in much the same way. I usually rinse the nib unit first under a dripping tap, expel the final drops of ink and draw up clean water from a cup, expel, rinse, repeat, until the water that comes out of the pen is clear. This is the beauty and much beloved aspect of piston fillers: the draw up loads of ink and clean out pretty easily. I have not yet had the need to take my pistons apart for lubricating the seal, but when I do, I will definitely do a post on that. Not using pen flush or detergent when cleaning your piston filler, will help keep the piston greased up longer. Use it if you absolutely must because of a sticky ink, but with regular inks just plain water will do fine for cleaning. Now, on to the pens!


TWSBI Eco Clear, 1.1 stub

TWSBI has revolutionized piston fillers by bringing very affordable, self-maintenance-friendly piston fillers on the market. And demonstrators to boot! This is very nice, because this allows you to see the mechanism in working order. And look at your ink sloshing around in your pen during meetings. The TWSBI Eco has an ink capacity of a whopping 1.76ml. The pen has a nice range of steel nib options from extra fine through B and a 1.1 stub as shown above. The pen is made of resin, has a screw-on cap which pushes to post very securely on the blind cap. The rubber ring that secures the cap keeps you from operating the piston knob by accident. However, posting the cap will make the pen as long as Harry Potter’s wand. The unposted pen is long enough to be used by hands of any size. A very decent and fun entry piston filler, for around $29-35 depending on where you live.


Lamy 2000, medium nib

The Lamy 2000, or L2K as affectionately dubbed by aficionados, was designed in the mid 60s at the request of Dr. Manfred Lamy, son of Lamy founder C. Josef Lamy, by Gerd Muller, who had previously been an influential designer at Braun. Manfred Lamy wanted to bring an entirely new clear and functional pen design on the market, aimed at “successful middle-aged men… image-conscious but tended toward understatement”, according to the Lamy website. Well, they certainly succeeded in bringing a very successful new design on the market, because more than 50 years later, this design is still much loved and widely coveted. I used to belong to the “nah, I do not care for that boring black pen” school for a long time. Until I took a better look at the zeppelin shaped body. Hmmm, did I actually start to like the pen…? Still there was that cap that did not yet ring my bell. But then again, I was very curious about the Lamy 2000 nib.

At a Pen Show, I got to try The Pencilcase Blog’s Lamy (thank you for trusting me with your pen, Dries) and was sold. The clip is spring-loaded, which I absolutely love. And I finally started to appreciate the contrast of the cap and body combined with the feel of the Makrolon material. The way in which the blind cap fuses seemingly seamlessly with the body. So when I spotted a set of a fountain pen and ballpoint Lamy 2000 at an auction site, I set a limit for myself and even managed to stay under it. Very happy to have taken that step! Now for some statistics: the Lamy holds 1.35ml of ink, it comes with a 14k springy (not flexy, just springy) nib available in EF through OBB. The material is Makrolon, a black fibre-glass, and stainless steel. The L2K has a snap cap and is portable, but I love using it unposted because of the nice body shape. The hooded nib allows for using the pen held close to the nib (not too close though, the pen will then be pushed backwards out of your grip) or anywhere on the body because of its sleek design. A new Lamy 2000 Makrolon will set you back about $150.


Aurora Optima Burgundy, medium nib

I must be honest and tell you up front that this is the darling of my piston fillers. It is such a classic beauty! The nib writes like a pencil and it sings to me when it’s happy with the paper I use her on. And just look at that material… But first things first. Aurora is an Italian pen brand that was founded in 1919 in Turin. Up to today, it is still housed in its original Turin factory. All the parts of this pen are made in the factory; this goes for the nibs as well. The trims are hand-finished, the pen has an ebonite feed which is a lovely dark red and a hidden ink reservoir. Because of the pencil-like feel of the nib, I love using this pen for doodling and faux calligraphy. But this is also the pen I use as my bullet journal pen or when I have to fill in or sign documents. It gives that moment a bit of extra meaning. I love the grip on the section, which surprised me pleasantly because I hold pens pretty close to the nib, but the step between section and nib is so pleasant to the touch, that I can write with this pen for hours without feeling cramped up. And of all the pens dealt with here, this has the most smooth running piston. The pen is cleaned and filled in no time. The nib unit can be screwed out completely for a good rinse. Or for switching up between nib sizes. Which is a very nice aspect of this design.

I find myself staring at the scroll work on the nib when I use the pen, it’s so pretty. Oh yes, back to business, sorry… the 14k nib comes in many options, from EF through OB, plus stub and italic. The piston holds an impressive 1.43ml of ink, and the ink window between section and body allows you to see how much ink you have left. The body is made of Auroloid which contains antique celluloid materials. The depth and colors of this material are notoriously hard to justify in pictures. My friend bought herself an Optima in Nero Perla and that is a very sexy see-through material. You can just see the nib peep at you through the cap… very alluring. The cap screws on the body and can be pushed to post. This will lengthen the pen for people with large hands, although the pen will still rest easily between index finger and thumb when unposted. The Auroloid feels very organic to the touch, it’ll warm up just ever so slightly without becoming slippery.

The Aurora is a staple in my every day carry and as such one of the pens I use on a daily basis. The nib is one of my rare mediums and the one I like using the best. If you get the chance to try one out, by all means do so. The price ranges from $450-495, and there are sellers who are currently having pretty good offers on Optimas… just saying… It is a bit of an investment, I am aware of that, but one that will bring you pleasure every time you use it. So, for a special occasion or just to treat yourself to a beautiful, functional writing instrument, this is definitely a pen I would recommend.

To round up, a couple of side-by-side images.
