OPUS 88 OMAR Fountain Pen - Christmas

Festive, oversized, and built for long writing sessions

The Opus 88 Omar Christmas edition is a bold demonstrator fountain pen with a warm, seasonal colour way and serious ink capacity. Designed around an eyedropper filling system with a shut-off valve, it’s made for writers who want flow, reliability, and the freedom to use expressive inks without constantly refilling.

What sets it apart

• Large ink capacity for extended writing
  
• Shut-off valve helps prevent leaks during travel
• Oversized body offers excellent comfort for longer sessions
  
• Smooth steel nib with consistent, controlled flow

Feel in the hand

This is a pen that encourages you to slow down and enjoy the act of writing. The matte acrylic used in this colour way improves grip and creates a sense of connection to the writing process. It feels generous and slightly indulgent, like using more ink than you need, simply because you can.

Who it’s for

• Writers who prefer high capacity pens
• Fans of the low sheen acrylic look
• Those who like larger, more ergonomic pens
  
• Anyone wanting a distinctive, seasonal design

Not for

• Those who prefer compact or pocket pens
• Users who want cartridge or converter convenience
• Minimalists who prefer understated designs
• Writers who need quick, one handed usability without managing a valve

Practical tips

• Open the shut-off valve slightly while writing
  
• Fill slowly to minimise air bubbles
  

FAQs

Is the shut-off valve necessary to use?
Yes. You’ll need to open it slightly while writing to allow ink to flow to the feed.

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

Is it suitable for beginners?
Yes, though the eyedropper system requires a bit more care than cartridge pens.

Can it handle document and shimmer inks?
Yes, the large reservoir works well with document or shimmer, but regular cleaning is recommended.

How large is the pen?
It’s a full-sized oversized pen, designed for comfort rather than portability.

Can the cap be posted?
No, and it isn’t needed due to the pen’s length and balance.

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