Penlux Masterpiece Delgado Beta Review: A Fountain Pen Inspired by the Betta Fish

Introduction

Penlux is a Taiwan-based company that spent more than 15 years building private label projects before launching pens under its own name around six or seven years ago. In the United States the brand is distributed by Itoya, the same company that distributes Sailor, so Western buyers are starting to see more of Penlux’s work.

The Masterpiece Delgado Beta is a new model just reaching US retailers, and it is the first pen in the Delgado creature collection, a series inspired by the natural beauty of creatures in nature. As the name suggests (delgado means thin in Spanish), this is a smaller and thinner take on the original Masterpiece, and it is more than just a scaled-down version.

Unboxing and First Impressions

The pen arrives in a box with the Penlux logo peeking through a window in the lid. Inside you get a use and care guide, a debossed certificate of authenticity, and a translucent plastic card carrying important handling information: removing the nib and feed is possible, but removing the section or piston knob will damage the pen beyond repair.

Placing that warning on the plastic rather than burying it in a booklet is a smart touch. It is the kind of information that is easy to skip in a care guide, and Penlux deserves credit for presenting it in a way that actually gets noticed.

Design and Materials

The Beta is named for the betta fish, also known as the Siamese fighting fish. The pen is made from PMMA resin, with a glistening deep blue body complemented by stark black and bright yellow that together give it a scaled effect. Crushed resin, where material is formed, chopped up, and reformed, is not usually a favorite technique, but here it serves a clear purpose of evoking a betta fish, and it does that well. Because of the nature of the material, no two pens will look alike.

The rounded cap transitions into a gold-plated clip that is wide at the top and tapers down to a wheel, which makes the clip easy to operate. The cap band is gold plated and stamped with the Penlux name, and the barrel tapers evenly down to a gold band marking the start of the rounded piston knob. Compared to the standard Masterpiece, the clip and band differ, so the Delgado is genuinely a different design rather than the same pen made smaller.

Nib and Section Details

Under the cap, which twists off with two and a half rotations, sits a gold-plated stainless steel Jowo number six nib available in fine, medium, and broad, plus a 1.1 stub at an additional cost. There are also upgrade options: a 14 karat gold flex nib, or an 18 karat gold nib in fine or medium. The feed is plastic.

The section begins with a slight flare and angles up at a steady angle to the threads, then continues straight before a small step up to the barrel. It is not the longest section, and a grip near the end will rest on the threads, though they are not sharp or uncomfortable.

Size, Posting, and Balance

The pen is plenty long enough to use unposted. The cap posts deeply and securely, and the tapered clip band design minimizes the step from cap to barrel, so the transition is smooth rather than something that rubs against the hand. The cap is light, so posting does not make the pen unwieldy, and while this is not the heftiest pen, what weight it has is well distributed even when posted.

Writing Performance

The review unit carries a broad stainless steel Jowo nib, paired with a dark blue-green ink for the writing sample. The broad nib writes very well: fairly smooth, with decent ink flow, and it keeps up with fast writing without problems. It is rather stiff, so do not expect much line variation, and reverse writing is a little scratchy.

For everyday writing, the nib strikes a good balance between smoothness and control, and the stiffness is more a matter of preference than a flaw.

Should You Buy the Delgado Beta?

The Penlux Masterpiece Delgado Beta sells for $136 from a number of retailers, which feels like a very reasonable price for what you get. The pen is well constructed with quality parts, the themed resin is genuinely interesting, and the creature series looks like a line worth following.

If you enjoy piston fillers with personality, a smaller and thinner profile, and resin work that actually tells a story, the Beta makes a strong case for itself. And with more creature-collection releases on the way, this is a good entry point into the brand.

Conclusion

The Delgado Beta shows Penlux building on the Masterpiece platform with real design intent rather than a simple size change. Between the betta fish-inspired resin, flexible nib options, sensible $136 pricing, and careful touches like the prominent handling warning, it is an easy pen to recommend for anyone looking for a well-made piston filler with character.
