# 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

### FAQs

**How does the filling system work?**  
It uses an eyedropper system. Fill the barrel directly with ink, then use the rear knob to control flow via the shut-off valve.

**Do I need to add silicone grease on the grip threads to prevent leaks?  
**No, the design includes a thick o-ring already.

**Is the finish glossy or matte?**  
The Omar Brown has a more traditional glossy acrylic finish, giving it a smoother feel and clearer light reflection.

**Is it suitable for everyday use?**  
Yes. Its large capacity and reliable flow make it well suited to daily writing, especially for longer sessions.

**Can it handle document and shimmer inks?**  
Yes, though regular cleaning is recommended to prevent buildup in the feed.

**How large is the pen?**  
It is an oversized pen designed for comfort and ink portability.

**What other nibs is it compatible with?**  
Other size #12 JoWo nib units and also the nib unit from the Pilot Parallel art pen.
