HongAn M2 Pocket Fountain Pen Review: A Small Pen That Writes Like a Big One

Introduction

Pocket pens inspire a particular kind of loyalty. Not everyone carries one, but the people who do tend to really like them, and the HongAn M2 seems built squarely for that group. It is a small aluminum fountain pen, it is genuinely affordable, and it has one feature that most pocket pens in this price range simply do not include. We spent time with the M2 to see whether it earns a spot in a jacket pocket.

The short version: it is comfortable, reliable, and it wrote beautifully straight out of the box. There are a few caveats worth knowing about, but overall there is a lot going for it here.

Design and Build Quality

The M2 arrives in a cardboard sleeve around a small hinged metal tin, which is a nice touch. Once the soft insert is removed, the tin makes a neat little desk case for pens or small items. Inside is the pen itself: a streamlined, compact aluminum body with anodized finishes available in army green, orange red, and the all-black stealth version shown here.

Next to a standard full-size pen like a Pilot Metropolitan, the M2 is unmistakably a pocket pen. The aluminum construction is claimed to weigh only about 12 grams for the barrel section, so it is very light. Details are handled well: a spring-loaded clip, a blind-engraved HongAn M2 marking on the cap, and a cat-themed yin-yang style motif on the cap top that is honestly kind of charming. The cap is large because it is meant to be posted, and it posts securely, turning the short pen into a comfortable full-length writer. Everything is nicely rounded off with no sharp edges, and the grip section is large enough to hold comfortably despite the pen’s size.

Writing Performance

Out of the box, the M2 wrote immediately and has not run dry, skipped, or hard-started since. The nib is a #5 fine steel nib with a plastic feed, black coated to match the pen. One note: the online listing described a “titanium black extra fine soft nib,” but this unit feels, handles, and writes like a standard steel fine nib, so that description may be a typo or refer to another variant.

Writing is smooth and nicely balanced in wetness, not excessively wet but never dry. Black-coated nibs sometimes produce a specific type of feedback because the tipping is coated too, but this one was pleasant to begin with, and that coating usually wears in over time anyway. Reverse writing works without issue, effectively turning the fine nib into a crisp extra-fine, and it does not dig into the paper. For a fine nib, this is a genuinely pleasant writer.

The Standout Feature: A Included Converter

Here is the feature that matters most: the M2 comes with a converter in the box. Many pocket pens omit one entirely or force you to buy a special mini converter separately, sometimes on pens that cost far more than this one.

The included converter is a smaller size, but it draws up ink without any issue and has a reasonable capacity. It looks proprietary, with a nipple that appears slightly wider than standard international, so cross-compatibility with other pens is uncertain. Either way, being able to use bottled ink out of the box is a real advantage at this price, and it is the kind of thoughtful inclusion that makes the M2 easy to recommend.

Things to Consider Before Buying

A few honest caveats. Unposted, the pen pushes it size-wise for larger hands; it is really meant to be used with the cap posted, which it does very well. The threads are a little sharp, though the section is long enough that they rarely interfere with your grip. The anodized aluminum can also scuff slightly where the cap posts, and long-term use may eventually reveal chips of the underlying silver aluminum. Some people find that wear charming, but if you like keeping pens pristine, a plastic-bodied pocket pen may suit you better. Eyedropper conversion is technically possible since the barrel is one piece, but metal bodies can sometimes interact with ink and cause discoloration, so it is not recommended.

The listed price sits around $27.98 Canadian, which makes the M2 very reasonably priced for an aluminum fountain pen that writes this well, especially with a converter included.

Buying Advice

If you like pocket pens, the M2 is a strong example of the type: light, well finished, comfortable when posted, and reliably ready to write. The included converter alone sets it apart from many competitors, including pens in a similar price bracket that require a separate converter purchase. If you prefer an unposted writing experience or a finish that never chips, look elsewhere, but for everyone else this is an easy recommendation at well under 30 Canadian.

Conclusion

The HongAn M2 does the simple things right. It is a well-made aluminum pocket pen with a spring-loaded clip, a pleasant fine steel nib, secure posting, and the rare bonus of a working converter included. It writes out of the box, it is affordable, and it is comfortable. What more could you wish for in a pocket pen?
