Esterbrook Niblet Review: A Pocket Fountain Pen With a Full-Size Nib

Introduction

The Esterbrook Niblet is one of the brand’s latest releases, and it takes a different approach from much of the company’s lineup. Rather than scaling down an existing design, it is a purpose-built pocket pen with a few genuinely interesting features, most notably a full number six JoWo nib hiding under a rather long cap.

There is also some backstory worth knowing before you buy. The Niblet was presented to Esterbrook’s parent company, Kenro, by their OEM manufacturer. That same OEM had already offered the identical model to another company, a Taiwanese retailer that sold it first at a slightly lower price. To many observers it looked like Esterbrook was copying another brand’s pen, when in reality both versions came from the same factory. In our view, Kenro was largely an innocent bystander in the situation. The other company no longer offers the pen, so the only way to buy it now is through Esterbrook retailers.

Design and Finishes

The Niblet is available in several finishes: Botanical Garden, Raven, Tortoise, Sea Glass, Honeycomb, and Nouveau Blue. All use what is often described as a crushed-ice resin technique: the resin is ground or chopped into small pieces, then reformulated with a binding resin of a contrasting color. The result is a distinctive, speckled translucency that photographs well and makes each pen look a little different from Esterbrook’s other offerings.

Shape-wise, the cap is straight and fairly long, engraved with the Esterbrook company name, with a roll stop at the end. The barrel steps down from the cap with a medium step, runs straight, and finishes in a slightly rounded end. One clever detail: there is only a single set of threads, shared between capping and posting. Because they sit far back in the barrel, they stay out of the way when you write unposted.

The Nib

Under the cap sits a surprising feature for a pen this size: a stainless steel number six JoWo nib. We enjoy seeing larger nibs on smaller pens, and this one gives the Niblet real presence when uncapped. It is available in extra fine, fine, medium, broad, double broad, mini stub, fine flex, and extra fine flex.

The section begins with a slight flare, angles down and back up, and carries a gold band. It is not a thick section, but it is far from uncomfortable, and the pen is long enough unposted that you do not need to post it. If you do post, the roll stop ends up facing up, which looks tidy, and the posted length is close to most standard-size pens.

Filling System

The Niblet is a cartridge-converter pen. It accepts standard international cartridges, and an included Esterbrook converter lets you use bottled ink. The converter is slightly larger than the original Kaweco converter, and the fact that it is provided means you are not locked into cartridges.

A practical bonus: the converter is compact enough to work in other pens in a collection that cannot fit a full-size converter, which adds value beyond this pen alone.

Size and Comfort

The Niblet is a pocket pen, but on the larger side of that category. Next to a Kaweco Sport it is very similar in size, and it also sits comfortably alongside other compact pens like the Kaweco Liliput, BENU Pixie, Ensso Piuma, Schon DSGN Pocket Six, and the Pocket Fox. When posted, it is noticeably longer than the Sport and Liliput and approaches standard pen territory.

For anyone who finds ultra-short pens cramped but wants something genuinely pocketable, this sizing hits a useful middle ground.

Writing Performance

In testing, the number six JoWo broad nib wrote more than smoothly, with just a touch of feedback rather than a glassy feel. Ink flow sat on the medium side, and the feed kept up nicely during fast writing. Reverse writing was a little scratchy with slightly inconsistent flow, which is worth noting if you rotate nibs often.

With Esterbrook’s own scarlet ink, the light, slightly red-orange red looked pleasant on the page, though writers wanting a more saturated red may prefer deeper options from other brands.

Buying Advice

At approximately $155, the Niblet is not cheap, but the price sits in line with comparable pocket pens, including some higher-end Kaweco models in the same market segment. You are paying for a distinctive resin, a full-size JoWo nib, and a thoughtful shared-thread posting design.

If you want a pocket pen that does not feel like a compromise, the Niblet is an interesting addition to the Esterbrook lineup and worth a close look. For fans of the brand, the book Fountain Pens of Esterbrook by Paul Hoban makes a compelling companion, covering both the historic side of the company and its modern pens.

Conclusion

The Esterbrook Niblet stands out because it is its own design rather than a shrunken version of an existing pen. A number six JoWo nib, comfortable unposted grip, included converter, and eye-catching crushed-ice resins make it one of the more interesting pocket pens in this price range.
