Esterbrook SD Scarlet Oversize Review: Hollywood Glamour in a Fountain Pen

Introduction

The Esterbrook SD Scarlet Oversize is a fairly new release built around a familiar idea: take an already well-liked pen and give it more presence in the hand. The SD line has seen several versions, and the Scarlet takes the oversized route for the first time in this colorway. Priced at $200, with the standard-size SD at $156, it positions itself as a mid-tier pen with some genuinely thoughtful details. This review covers the design, nib options, how it writes, and the companion Scarlet ink that launched alongside it.

Unboxing and First Impressions

The pen arrives in a retro-looking outer box, inside of which sits an inner box with a knit-textured exterior. Alongside the pen you get a spare cartridge, an Esterbrook branded polishing cloth, and a small card covering company history with a QR code that links to the warranty information. The QR code approach is a smart one from a manufacturer’s perspective: a small card is far cheaper to produce than a full manual, and the code gets you to everything you need online.

Design and Materials

The SD Scarlet is a cigar-shaped pen inspired by the golden age of Hollywood, which the company describes as a nod to the glamour and silver-screen starlets who made Los Angeles famous. It comes in two trims: gold trim, and this model’s palladium trim. The oversized body is made from a premium vibrant red crushed acrylic with hints of blue woven through it. The construction involves taking a base red resin, chopping it into pieces, and reforming it with a second acrylic as the binder, which is why the blue appears in the cracks between the red sections. Crushed acrylic is not everyone’s favorite look, but this one works well, with some subtle chatoyance visible in the red.

The cap comes to a rounded point and is a single piece with a slot for the clip, which is basic in design but fits the aesthetics well. The clip end is engraved with the company name and filled with silver lacquer. The barrel tapers down at an even angle to a rounded end slightly narrower than the top of the cap.

The Cushion Cap and Usability Details

One notable feature is the cushion cap, a spring-loaded inner cap similar to mechanisms used on pens from brands like Platinum. The idea is that the tighter seal around the nib limits air exposure and helps prevent the nib from drying out. On this pen the spring is fairly strong: it engages about a third of an inch before the threads meet, so you need to apply a bit of intentional pressure to cap the pen. It is wise to hold the pen ends in your palm while capping so the spring cannot shoot either end loose. It is a good technology in principle, but the spring rate could be softer.

The cap unscrews with just half a rotation, which is convenient. The pen is long enough to use unposted, and posting does not work well anyway, as the cap sits loosely on the barrel. The section starts with a slight flare and angles up gently before meeting large, blocky metal threads, then a stair step to the barrel. On the oversized model the section could be slightly thicker, since a full grip can spill over onto the threads, though they are neither sharp nor uncomfortable and the stair-step edges are smooth enough.

Nib and Filling System

The palladium trim model carries a number six JoWo stainless steel nib in silver, while the gold trim version pairs a gold-colored nib. Sizes range from extra fine, fine, medium, and broad to a 1.1 stub, and many retailers also offer custom grinds from Gena Salerno: the Journaler and the Scribe, for an additional $40. The pen is a cartridge-converter design that uses standard international cartridges, with a converter included in the box.

How It Writes

The medium stainless steel nib on the test unit runs a bit rigid, with noticeable feedback and a slightly scratchy character, especially on side strokes. Smoothing the nib slightly would be an easy fix. Ink flow is decent, reverse writing is quite sharp, and the feed keeps up without issue during fast writing. In hand, the oversized dimensions are the real appeal: the size genuinely works for longer writing sessions, and it is easy to see why someone who already owns a standard SD would want to add the oversize version too.

Size Comparisons

Against the standard SD, the oversize version is noticeably larger, and it sits comfortably in the company of big flagship pens. It is fairly similar in size to a Sailor King of Pen in ebonite, and it compares sensibly with pens like the Montegrappa Elmo 02, the Diplomat Elox, the Pelikan M805, and the Delta Dolce Vita Oversize, both capped and uncapped. If you like large pens, this one belongs in that conversation.

The Companion Scarlet Ink

Esterbrook released a matching Scarlet ink alongside the pen. It is a nice, vibrant, orange-leaning red that comes in a 50 milliliter bottle with a large neck and the Esterbrook eternity logo, a mirrored pair of E shapes. On cheaper, absorbent paper it showed a fair amount of feathering in testing, repeated on a second attempt. Next to Three Oysters Chili Red it reads warmer, while Diamine Poppy Red comes across as the more vivid, redder red of the group.

Buying Advice

At $200, the SD Scarlet Oversize feels reasonably priced for what you get: premium crushed acrylic, a reliable JoWo steel nib with plenty of size and grind options, a converter in the box, and thoughtful details like the cushion cap. The main caveats are the strong cap spring, a section that could be a touch thicker, and a nib that may need light smoothing out of the box. If you prefer smaller pens or skip oversized models, the standard SD at $156 is the better fit. If big pens work for you, this is a compelling pick.

Conclusion

The Esterbrook SD Scarlet Oversize is an interesting addition to the Esterbrook lineup. It combines eye-catching materials, practical usability, and a generous size that suits long writing sessions. With minor nib tuning, it is easy to see why an oversized model like this would find its way into a collection, paired naturally with the vibrant Scarlet ink that was made for it.
