Pilot Custom 845 Urushi Black Fountain Pen

Pilot Custom 845 - Urushi Black Fountain Pen

The Pilot Custom 845 - Urushi Black Fountain Pen is the perfect balance between Japanese craftsmanship and writing performance. First released in 2002, this model stands out for its exceptional build, generous proportions, and deep black urushi lacquer that develops a soft patina over time.

Design and materials

Its body is made of hand-turned ebonite, a warm and lightweight material traditionally used in high-end writing instruments. The lacquer is applied using the Roiro Urushi technique, a demanding multi-step process where each layer is carefully polished to achieve a brilliant and refined finish. The result is a fountain pen that is both elegant and durable, with a visual depth that reflects the Japanese spirit of refinement.

Nib and filling system

The pen is equipped with a No 15 bicolor nib made of 18K gold (7501000), delivering smooth ink flow and comfortable feedback. The filling system supports both Pilot’s CON 70 high-capacity converter and standard ink cartridges, offering flexibility and convenience for every writer.

Nib variations

The Custom 845 is available in four nib sizes to match different writing preferences:

• F (Fine) – Ideal for precise strokes and compact writing.
• M (Medium) – Well-balanced for everyday writing and signatures.
• B (Broad) – Suitable for bold, expressive handwriting.
• BB (Double Broad) – Delivers generous ink flow for strong visual presence.

Box contents

The Pilot Custom 845 comes in an elegant presentation box and includes a CON 70 converter, one Pilot ink cartridge, and official documentation.
