OPUS 88 OMAR Fountain Pen - Brown
Warm, translucent, and quietly refined
The Opus 88 Omar Brown is a large format demonstrator fountain pen built for long writing sessions and deep ink capacity. Finished in a rich, tea-toned acrylic, it offers a more classic, polished look compared to brighter or more stylised colour ways. Under light, the semi-translucent body reveals your ink with a warm, amber glow. Designed with an eyedropper filling system and shut-off valve.
What sets it apart
- High capacity eyedropper system for extended writing
- Shut-off valve helps prevent leaks during transport
- Glossy translucent brown acrylic with depth and clarity
- Oversized body for comfortable use
- Smooth steel nib with reliable, even flow
Feel in the hand
This is a calmer, more grounded version of the Omar. The brown acrylic softens the demonstrator look, giving it a more traditional, almost vintage tone. It feels steady and dependable.
Who it’s for
- Writers who want a high capacity daily pen
- Those who prefer classic, understated colour ways
- Fans of demonstrators with a more subtle presentation
- Users who enjoy larger pens for comfort
- Nib explorers who enjoy nib swabs and experimentation
Not for
- Those who prefer compact or lightweight pocket pens
- Users who want cartridge or converter convenience
- Anyone drawn to bright, high contrast finishes
- Writers who need quick, one handed usability without managing a valve
Practical tips
- Open the shut-off valve slightly while writing
- Expect a smoother, glossier feel compared to more matte Omar finishes
