Premium Ebony Series "Kuro Matsu"
Distinctive Ebony Accessories Crafted for HHKB
Genuine materials for something you touch every day.
The Ebony Palm Rest and Ebony Keycaps by Matsuba Factory are crafted from rare natural ebony using precision woodworking techniques. Designed exclusively for HHKB, they enhance both the typing experience and the understated elegance of the keyboard.
Each piece is carefully finished to preserve the deep color, fine grain, and smooth touch unique to ebony, while maintaining the functional beauty and tactile experience that define the HHKB.
The Quiet Presence of Rare Ebony
Ebony is an exceptionally dense and hard hardwood, distinguished by its deep black-brown color and remarkably fine grain.
As light shifts and viewing angles change, the wood reveals subtle variations in tone and depth that cannot be replicated by resin or painted finishes.
Rather than drawing attention to itself, ebony naturally complements HHKB's clean, minimalist design, adding a quiet sense of refinement to your workspace.
Because it is a natural material, every piece is unique, with its own distinctive grain and character.
Premium Ebony “Kikko-Naguri” Palm Rest
Smooth to the Touch. Natural in Use.
he Ebony Palm Rest is designed to match the height and front profile of the HHKB, providing natural support for the wrists and palms during extended typing sessions.
Carefully polished to bring out the dense character of ebony while preserving the warmth of natural wood, it offers a smooth yet reassuringly solid feel. Its proportions create a seamless connection with the keyboard, enhancing not only comfort but also the visual harmony of your desk.
Precision Craftsmanship in Every Detail
Drawing on the precision woodworking expertise developed through decades of model-making, Matsuba Factory carefully shapes, polishes, and finishes every palm rest by hand.
Because ebony is exceptionally hard, every curve, edge, and surface requires meticulous attention throughout the manufacturing process. The result is a palm rest designed to feel comfortable every time you sit down to type.
With years of use, the wood develops a richer luster and deeper character, becoming uniquely yours.
Ebony Keycaps
The Distinctive Feel of Natural Ebony at Your Fingertips
The Ebony Keycaps are a unique customization that replaces HHKB keycaps with ones crafted from solid natural ebony.
Their rich, deep color blends naturally with the HHKB, creating a quiet presence that differs from conventional resin keycaps. Every surface, edge, and contour is carefully refined to deliver the smooth feel and dense character of ebony with every keystroke.
Precision in Every Detail
Keycaps are components where even the smallest dimensional variation can affect both appearance and typing feel.
Drawing on the precision woodworking expertise developed through decades of model-making, Matsuba Factory carefully manufactures each keycap with close attention to spacing, height, alignment, and the relationship between the keycap and its switch stem.
The standard unprinted design allows the natural grain and sculptural form of ebony to take center stage, complementing the clean, minimalist aesthetic of the HHKB.
Replaceable Stem Design for Long-Term Use
The wooden keycap body and stem are designed as separate components, allowing the stem to be replaced if maintenance is ever required.
Should a stem become damaged, the ebony keycap itself can continue to be used, reducing unnecessary waste of this rare material.
Designed to be repaired rather than replaced, these keycaps are made to be enjoyed for years to come.
A Unified Typing Environment in Ebony
Combining the Ebony Palm Rest with the Ebony Keycaps creates a refined sense of continuity between the HHKB and your workspace.
Paired with the solid wood HHKB Desk, the desk, palm rest, and keycaps come together as a cohesive environment shaped by a shared design philosophy.
The subtle variations in grain and color unique to natural wood create a harmony that synthetic materials simply cannot replicate.
Matsuba Factory
Crafted to Last
Ebony is exceptionally hard and highly durable. As a natural material, however, it may respond to significant changes in temperature or humidity, excessive dryness, or strong impacts, which can result in movement or fine cracks over time.
At Matsuba Factory, we carefully consider the unique characteristics of natural wood throughout every stage—from selecting the material to machining and finishing—to create products that can be enjoyed for years to come.
Should maintenance ever become necessary, we assess each piece individually and, whenever possible, offer repair or replacement of components to help extend the life of your product.
The Philosophy Behind the Ebony Collection
The HHKB is a keyboard that becomes more familiar with every use, growing into an indispensable tool over time.
We believe the accessories that accompany it should do the same—not products to be replaced after a short time, but objects that become more personal and rewarding with years of use.
Through the quiet beauty of ebony, the warmth of natural wood, and the comfort made possible by precision craftsmanship, the Ebony Palm Rest and Ebony Keycaps by Matsuba Factory are designed to make every typing session a little more special.
