The Opus 88 Harmony Brown brings together the classic proportions of the Harmony collection with a warm and sophisticated colour palette. Crafted from richly marbled brown resin, the pen reveals flowing amber and caramel tones that create depth, movement and subtle variation across its surface.

The resin pattern gives each pen its own individual character, while the darker finials frame the design and add definition. Rose gold trim provides the perfect complement to the warm brown tones, lending the Harmony Brown an elegant and refined presence.

The pen features Opus 88's Japanese-style eyedropper filling system, offering a generous ink capacity and excellent practicality. To fill the pen, simply unscrew the grip section and use the included eyedropper to fill the reservoir before reassembling it.

An integrated shut-off valve controls the flow of ink between the main reservoir and the nib. During longer writing sessions, the end blind cap can be loosened slightly to allow continuous ink flow. When fully closed, the valve isolates the reservoir, providing additional security when carrying the pen or travelling, including by air.

The Harmony Brown is fitted with a JoWo #6 stainless-steel nib and a threaded cap. Combined with the rose gold trim and richly patterned resin, these details create a fountain pen that balances dependable everyday performance with a distinctly premium aesthetic.

The Opus 88 Harmony Brown combines expressive marbled resin, warm rose gold accents and the brand's characteristic high-capacity filling system in a design that feels elegant, distinctive and unmistakably Opus 88.
