About the Marble 60
The Marble 60 is a 60% keyboard carved entirely from real marble. It’s the result of combining traditional stone craftsmanship with modern mechanical keyboard design — a project that turns a functional tool into a piece of art.
The idea started back in 2024, when one of our team members — whose family has been in masonry for generations — suggested bringing his heritage into our shared passion for keyboards. We were optimistic at first, thinking we could launch by late 2024, and even managed to produce an early prototype that year. It wasn’t perfect, but it showed us something incredible: the sound and look of marble in a keyboard is truly one of a kind.
From that point on, we’ve never stopped refining it. We tested multiple workshops, broke more than a few tool tips, experimented with finishes and marble types, and kept iterating until we found the right partners who could meet our vision. Every step has been about balancing the natural character of marble with the practical needs of a keyboard.
I personally keep two prototypes for every iteration — one with an MX PCB and one with a Hall Effect PCB — swapping keycaps of different profiles to test compatibility. While CAD helped guide the design, the truth is marble can’t be shaped by machines alone; every case still requires a mason’s hand for the finishing touches. That’s why I’ve spent countless visits at the workshop, working side by side with artisans to bring this project to life.
The design is simple and intentional: marble first, keyboard second. We didn’t chase trends like low front height, because reducing the case structure also reduces the resonance that makes the sound so unique. Instead, we embraced the natural density and texture of marble. For comfort, we recommend pairing it with a wrist rest.

The latest prototypes are the closest we’ve ever come to the vision we started with — balancing durability, machining, and the unique acoustic signature of marble. Each iteration has been tested with different PCBs and keycaps to ensure real-world compatibility.
What makes this project different is that the final stages of production can’t be done by machine alone. Every case still requires a mason’s expertise, which means each Marble 60 carries the human touch of traditional craftsmanship.
Our next step is finalize details like marble variants and PCB, plate for the kit. We are aiming for a late 2025 group buy.
Stay tuned for more photos, updates, and testing content — and please share your thoughts in the IC form to help us shape the final release.
