Mass - Brass

A pen as sculptural object

A new kind of writing tool from Kakimori, this desk pen pairs a ballpoint pen with its own stand, blending into your space like a sculptural piece, ready to write at any moment.

In a time when we carry pens less often, this is a pen worth leaving out on show — one that invites our touch and anchors everyday writing. We set out to create just the kind of tool that inspires us to write.

At home, anywhere

Evoking a mass of metal machined from solid brass, the pen blends effortlessly into any space, setting or occasion — perfect for guestbook entries at hotels and shops, or jotting down a quick note or thought at home.

It is designed to feel equally at home displayed on a bookshelf, in the kitchen or the living room.

Left unfinished, the brass develops a beautiful patina with time and use — a material that ages and evolves uniquely with you.

Details considered for comfort

Designed for a seamless integration of the front cone, the pen gives the illusion of a single, streamlined mass that feels instantly pleasurable in the hand.

The pen comes fitted with the Schmidt easyFLOW 9000 medium refill. The slightly bolder line weight is well suited for signatures, while the low-viscosity oil-based ink delivers an effortlessly smooth writing experience.

Designed for easy replacement of the universal G2 refill, the pen ensures years of writing pleasure.

From design to function, every small detail has been considered with care — a quality that reveals itself the moment you put pen to paper.

Precision engineering to the ballpoint pen

The pen is crafted by Arai Precision, a manufacturer specialising in metal components for automotive and medical equipment industries.

Each piece is individually machined from solid metal using cutting-edge technology, making micron-level adjustments for a finish that feels exceptionally smooth to the touch.

Strikingly crafted from solid brass, this is a beautifully simple desk pen with enduring appeal. We invite you to welcome one to your desk.
