The copper nib was born from the desire to create a durable and practical dip pen nib. Enjoy a variety of line thicknesses, from fine to broad, by tilting the nib at different angles. Compatible with most nib holders, including those from our range.
*Nib holder sold separately.
The nib was designed by Yuto Yamazaki of the Alloy design studio, based in Kuramae. The tip was carefully rounded and polished, offering an exceptionally smooth and surprising writing experience. Perfected after many iterations, this innovative nib is one of a kind.
Ideal for artwork, the nib can be used at different angles to paint like a brush or create fine, detailed lines.
Material Properties
Copper naturally oxidizes when exposed to air. Your new nib may show a reddish tint or some spots; this is normal and does not affect its performance. Thanks to the metal’s natural softness, the tip gradually rounds with use, producing bolder strokes and smoother writing over time. Enjoy a tool designed to evolve with your personal writing style.

Usage & Entretien
The initial ink flow may be slow due to the nib’s protective coating and will gradually improve after several rinses and ink applications.
The maximum writing angle is 45 degrees.
Insert the nib into the holder with a slight rotation until it is securely in place. To remove it, turn and pull slowly—a sudden pull may detach the nib assembly.
A strong impact on this precision nib can compromise the ink flow.
To prevent dried ink buildup in the grooves, rinse frequently with water during use.
The metal nib is recommended for use with Kakimori and Inkstand inks.
To remove stubborn dried ink, gently scrub with a soft toothbrush in water.
If you use detergent, choose a neutral product. Avoid alkaline detergents, which can damage the surface.

Born in Kuramae, the craftsmen's district
Since 2010, Kakimori has inspired writing from Kuramae, a workshop district in Tokyo. Inks with vibrant colors, metal nibs, carefully selected papers: each item is designed to make the act of writing simple and precious, every day.





KAKIMORI EXPERTISE
What makes these objects unique
Inks with bold colors
Kakimori inks are pigmented: dense colors that sit on the paper and stay there, without bleeding through the page.
Metal feathers, regular stroke
Stainless steel or brass nibs provide a smooth and consistent line, and can be cleaned with a simple gesture.
Carefully selected paper
Notebooks, envelopes, and letter papers are selected for their feel and ink durability.
Hand-finished
Caps, pen holders, and pen rests go through the workshop for a smooth and precise finish.
A craftsman’s district
Kuramae, between workshops and shops, is the birthplace of the brand. It is where everything is designed and tested.
Since 2010
A young brand that has made a name for itself among writing enthusiasts, in Tokyo as well as in Paris.
