Pocket fountain pen

Inventery Pen Pocket Fountain Pen Review.


Inventery Pen Company contacted me asking if I would like to review their pocket fountain pens here on the blog. All thoughts shared in todays post are my own.

Inventery Pen Company sent me a set of three fountain pens, all of the same design but in a range of different materials and finishes. One brass, one chrome and one a black onyx (which is a black oxide that is essentially some sort of finish applied to different metals giving it the final black colour finish). The Inventery pocket fountain pens are really interesting as they consist of a series of elements that allow you to tinker and play with your fountain pen.


Impressive presentation.

The first thing that struck me when I received my Inventery pens was the packaging. The box is small for a fountain pen with a very simple design. Inside the elements of the fountain pen are well presented showing you all the different parts. Nothing is hidden, it’s all simply displayed showing you exactly what you’re working with.


Tweaking and modifying the pocket fountain pen.

The big ‘thing’ with the Inventery pocket fountain pens is the ways it can be modified to the users preferences. You get all the parts when your order your pen, and you can modify it as much or as little as you want. Everything is based on a simple screw system, it’s just about finding what works for you.

On the cap there are a number of different options: clip, clip-less, stylus and keychain. In its pocket configuration you can use a standard size cartridge. There is then an extender which can be added to lengthen the pen to a longer format which allows you to use the longer Schmidt cartridge convertor.

Inventery describe their pocket fountain pen as a kit and that seems like a good description. For tinkerers I think this is a fab fountain pen.


There are a number of different nib options on the Inventery pocket fountain pen. The pens use the Schmidt FH241 nib. There are gold and chrome options in a range of different sizes. I have a medium nib in all three fountain pens but both the chrome and gold nibs.


The nibs have performed well and actually the lines are thinner than I was expecting from a Western nib. They are firm with very little flex, so great for writing with.


Using the Inventery pocket fountain pens.

To really get a feel for the different configurations I have set the pens up differently. One with the extender, one pocket and then the different caps.

Using the extender made the pen feel really long, especially in proportion with the width. Everything just seemed a little out of balance. Posting the cap when writing made it feel a lot worse. I wasn’t really a fan of this set-up.


The pocket configuration however was really nice. The barrel is just about long enough to write with unposted, but posting the cap felt much nicer. It didn’t mess with the weight or balance too much at all. The different cap options are good but personally I liked having the clip, simply because it meant my pen didn’t roll away. I liked the look of the clip-less cap but keeping the pen in one place proved tricky.

The one major consideration with this pen is the thin barrel. It almost feels like a pencil. This makes it a great pocket pen keeping everything small and light, but if you compare it to the Kaweco AL Sport, probably the most popular pocket fountain pen, there is a very big difference. The thinness could be an issue for some users.

Overall thoughts.

I have really enjoyed using these fountain pens for the past few weeks. The pocket version has definitely been my favourite set-up and much more comfortable to use. The Inventery pocket fountain pen is a really simple design but its made really well and by having the adaptable elements keeps it fun and exciting to use.

Thank you again to Inventery Pen Company for sending me their pocket fountain pens to test and review on the blog.
