Ensō Italia in Primary Manipulation 4: A Colorful Limited Edition Fountain Pen Review

Introduction

Fountain pens don’t usually arrive in materials this loud, and that is exactly the appeal here. The Ensō Italia in Primary Manipulation 4 takes a minimalist pen design and dresses it in one of the most colorful cast resins around, made by Jonathan Brooks of the Carolina Pen Company. This is a limited run of just 80 pens, priced at $295 US with a 14k gold nib, and it comes from a brand that clearly knows what a certain type of collector is looking for: something light, comfortable, and visually striking.

First Impressions and Design

Out of the box, the pen arrives in a magnetic-closure box with an outer sleeve, and the package includes both a cartridge (typically black) and a converter for bottled ink. Next to a Pilot Metropolitan, the Italia is about the same length but a little girthier, which puts it in very comfortable “one size fits most” territory. Even posted, it stays a pleasant, manageable size.

Up top, the finial uses the same material as the rest of the cap with a slight conical shape, and the ski-slope clip sits nicely tucked into the cap while still being usable. There is no center band, which is worth knowing if you are the type to over-tighten a cap. The tapering barrel ends in another conical shape, giving the pen a balanced profile. The section tapers down into a clean shape and the threads, while a touch sharp, sit far enough down the long section that you don’t feel them in a normal grip.

The Material Is the Star

It’s hard to overstate how much the Primary Manipulation 4 resin defines this pen. It is incredibly colorful, with genuine depth to the swirls, and it photographs just as well as it looks in hand. Colorful materials are not everyone’s cup of tea, but if you enjoy expressive resins, this is one to check out. The limited run of 80 pens adds to the appeal; if you want one, waiting too long is a real risk.

The light weight is a direct result of the construction: apart from the clip and the nib, there are almost no metal parts. If you prefer heavier pens, this one may not be for you. But for riders of the opposite preference, so to speak, especially people with arthritis or anyone who finds metal pens tiring, a light, non-fatiguing pen like this is a genuine advantage.

How It Writes

The nib is a 14k gold Bock unit in fine, engraved with the Ensō Italia logo and marked 14k 585 for the gold content. Fine is the only grade currently offered, which we’ll come back to. In use, it is a very pleasant writer: smooth, wet, and reliable, with no skips or hard starts. Fine nibs sometimes carry a scratchy reputation, but on coated paper this one is genuinely smooth, and any perceived scratchiness comes more from the paper than the nib.

Line variation is naturally minimal. You can coax a little extra flow by squeezing the section, but be careful: this is not a flex nib, and it isn’t advertised as one. Reverse writing works too, turning the fine nib into something closer to an extra fine that stays reasonably smooth without running dry quickly.

Things to Consider Before Buying

The converter is a standard acrylic unit that works like any converter would, and an eyedropper conversion looks plausible given the number of threads. There is already an O-ring in place, and a little silicone grease on the threads should quiet the O-ring squeak some people dislike. As always with eyedropper conversions, results aren’t guaranteed, so proceed with reasonable caution.

Now the caveats. The single fine nib grade is a limitation, and while stocking multiple nib grades may simply not be feasible at small volumes, buyers who prefer medium or broad will need to look elsewhere for now. The price of $295 US is not trivial either, even with the gold nib and limited-edition status, though it is far from the most expensive pen in this segment. It’s also worth being gentle when capping: with no center band and thinner materials at the cap lip, over-tightening is a small but real risk.

Buying Advice

If you love colorful resins, prefer a light pen, and are happy with a fine gold nib, this is an easy recommendation within its niche. The 80-piece limit means it won’t be around indefinitely, and ordering directly from Ensō has historically come with a 15 percent discount code (Italia PM4) that applies to any pen on their site, which softens the price meaningfully. If you need a broader nib or prefer heft in the hand, wait for a future run that suits you better.

Conclusion

The Ensō Italia in Primary Manipulation 4 is a charming, comfortable writer wrapped in one of the most striking resins you’ll find on a sub-$300 pen. The limitations are clear: one nib grade, a light weight that won’t suit everyone, and a cap that rewards gentle handling. But for collectors who value expressive materials and a smooth, wet fine nib in a limited batch, it delivers exactly what it promises.
