GRAF VON FABER-CASTELL Guilloche Rhodinert Fountain Pen (18K nib & converter)

Precision engraving and gold nib performance

The Guilloche Rhodinert fountain pen takes the signature engraved barrel and elevates it with a more technical finish. The Rhodinert coating gives the pen a stronger appearance, paired with the same handcrafted guilloche engraving beneath. Combined with a smooth 18k gold nib, this is a more modern, slightly edgier evolution of the Guilloche line.

Why you'll love it 

• Unique Rhodinert finish for a more contemporary look
• Individually engraved barrel with subtle tactile grip
• 18k gold nib delivers smooth, controlled writing
• Slim, lightweight profile ideal for daily use
• Distinct from standard black, with more depth and character

How it makes you feel

This pen feels more technical and deliberate than the standard Guilloche Black. The metal finish absorbs light rather than reflecting it, giving it a quieter look. In hand, it feels precise and composed, with just enough tactile feedback to stay engaging over long writing sessions.

Who's it for

• Professionals wanting a modern, understated luxury pen
• Users who like monochrome aesthetics
• Fountain pen buyers stepping into gold nibs
• Writers who prefer a lighter, more controlled form factor

Who's it not for

• Those who prefer warm tones or traditional finishes
• Users wanting a heavier, statement pen
• Anyone looking for high ink capacity
• Writers chasing flex or expressive line variation

Ink pairing suggestions

• Blue-black or graphite grey to match the subdued finish
• Deep violet or dark teal for subtle variation
• Cool greys or desaturated greens to enhance the technical look

Practical tips

• Flush before first use to ensure optimal ink flow
• Use the included converter for better ink variety
• Pair with smooth paper to highlight the nib performance
• Keep capped when not in use to maintain consistency
