From Raw Wood to Perfected Instrument.

A truly exceptional object is born from the harmony of seemingly opposing forces. At SIMEICHU, our entire process is a testament to our name’s deepest meaning: “四美具,二难并” (Sì Měi Jù, Èr Nán Bìng)—the rare and precious union of two worlds.

It is a journey that blends the patient soul of nature with the uncompromising precision of technology; the perfection of the machine with the irreplaceable touch of the human hand. Follow this journey to see how a SIMEICHU pen is brought to life.

The Soul of Material: Patience & Respect

Our journey begins not with action, but with listening. We hand-select rare and beautiful materials, chosen for their unique character and story. But a material’s true potential can only be revealed through patience. To ensure a lifetime of stability, every single block is left to naturally air-dry for months, sometimes even years. This slow, deliberate process allows the material to settle and reach a state of quiet integrity. It is our first commitment: respecting the soul of the material above all else.

Revealing the Form

Once a block has reached perfect equilibrium, our craftspeople begin to reveal the form held within. The large blocks are carefully cut, unveiling the inner beauty of the patterns. They are then milled into precise rods and bars that will become the pen’s core components. This stage is about preparing the canvas, ensuring every piece is flawless before it begins its dialogue with technology.

The Dialogue of Engineering

This is where one world meets another. Each component is secured in a high-precision Computer Numerical Control (CNC) machine. Here, a conversation unfolds between a digital blueprint and a natural soul. The machine carves and shapes the material with an accuracy measured in microns—a feat impossible to replicate by hand. This is not about dominating the material, but honoring it with a perfect form. It is how we achieve the flawless fit and the engineering tolerances required for our signature airtight seal.

The Union of Hands & Heart

Technology provides perfection, but the final spark of life comes from human hands. In this final stage, our skilled technicians assemble each pen with focused care, fitting the inner workings and seating the critical sealing components that ensure reliability.

Then, they install the heart of the pen: a high-performance nib, meticulously selected for its exceptional smoothness and consistency. But our work doesn’t stop there. Each nib is then individually tested and tuned by hand. Our standard is simple: it must deliver a flawless, expressive line from the very first stroke.

This is the moment where a set of perfectly machined parts is transformed into a truly soulful writing instrument, ready for you.

A Promise, Delivered

Before a pen can earn the name SIMEICHU, it must pass our rigorous final inspection, confirming that the rare harmony has been achieved. We check every detail, from the seamless fit of the cap to the flawless finish of the body. The result is more than a reliable tool; it’s a vessel for stories and a testament to a philosophy. Due to the unique character of our materials, no two pens are ever exactly alike. The one you hold is a one-of-a-kind creation, ready for a lifetime of connection.
