Wancher Sekai - Saihi Urushi - Aka-age Raden

Each Saihi-Urushi fountain pen is a unique, handcrafted item. The Saihi-nuri technique requires numerous work steps and particularly careful, reduced polishing to preserve the characteristic structures.
Fine traces of this process are deliberately left visible – a sign of true craftsmanship and not a defect. The Raden Edition also features shimmering mother-of-pearl inlays, which give the fountain pen fascinating depth and a luminous effect.

Saihi Urushi – An Imperial Art Form

Saihi Urushi originated in Huizhou, China, and has been revered as a royal art since the Song Dynasty. For centuries, it was so exclusive that only a few people outside the imperial court were ever allowed to touch it.
The technique was strictly guarded and almost disappeared in the 20th century.

Thanks to collaboration with highly specialized artisans from Fuzhou, Wancher is now able to revive this rare art form in the Sekai Saihi Urushi Collection – in a modern interpretation for writing instruments.

The Art of Saihi-nuri – Raw Natural Urushi

The heart of the Saihi technique is Raw Natural Urushi – an untreated lacquer with a strong color, distinctive texture, and semi-matte sheen.
It gives the wood exceptional durability and develops a beautiful patina over time:

– The lacquer brightens
– The sheen intensifies
– The surface gains depth

A Saihi-Urushi fountain pen ages like a work of art – visibly, gracefully, and uniquely.

The Traditional Saihi-nuri Process

The creation of a Saihi-Urushi fountain pen is complex and takes several months. Even though the technique has been adapted for writing instruments, the crucial steps remain unchanged:

1. Preparation of the Urushi
The raw lacquer is collected, filtered, and prepared for processing.

2. Building the Groove Structure
The characteristic grooves are individually hand-formed. They determine the later pattern and make each piece unique.

3. Gold Leaf (Kinpaku)
Finest gold leaf is applied to create a shimmering effect later.

4. 30–40 Layers of Colored Urushi
Applied layer by layer, each must dry completely. This process takes 3–4 months.

5. The Crucial Step: Sanding & Polishing
This determines the outcome. Too much polishing – and the gold disappears. Too little – and the surface remains rough.
Only experienced masters can achieve this balance.

Saihi Urushi + Raden – A New Dimension

The Raden Edition extends the traditional Saihi technique with fine mother-of-pearl inlays.
These shimmering Raden fragments are carefully integrated into the surface, creating a fascinating interplay of light, depth, and structure.

The combination of Raw Urushi, gold accents, and Raden makes this edition one of the most extraordinary interpretations of Saihi art available today.
