A Project for the Process

It’s a project designed not just for your desk, but for the deliberate, satisfying process of creating something uniquely yours.

For keyboards in the popular 75% layout category, the competition is fierce. The Love Letter 75 enters the space with a design that cuts through the noise. It’s outfitted with all the fundamentals for a perfectly tuned typing experience and shipped as a barebone kit so you can assemble it exactly to your liking. From its unique assembly system to its premium materials, this board cuts no corners.

A Build That Feels Different

To truly understand the benefits of a kit like this, you have to build it. The first thing you’ll notice about the Love Letter 75 is its thoughtful construction. At its core, that feel starts with the CNC-milled 6063 aluminum case, which gives the board a satisfying weight and a rock-solid foundation. But the real story is how it comes together. Instead of fiddly screws for the top and bottom case, Mage Studio designed a quick assembly ball catch system. The two halves snap together securely, making swaps and adjustments fast and simple. It’s a clever solution that respects your time without sacrificing a premium feel.

Dial In Your Ideal Sound

Complementing the physical structure is a comprehensive acoustic pack designed to help you dial in your ideal typing sound. This isn’t just a single piece of foam. The kit includes a full suite of dampening materials—Poron, IXPE, and EPDM layers for the plate, sockets, and case—to eliminate hollowness and shape the sound of every keystroke. It’s a complete setup that gives you granular control over the final sound profile.

Uncompromising Performance, Unchained

Inside, the Love Letter 75 houses some of the community's most sought-after features. It starts with tri-mode wireless connectivity, paired with a 4000mAh battery, to deliver true desktop freedom. Connect via low-latency 2.4Ghz for gaming, switch to Bluetooth 5.0 to pair with multiple devices, or plug in with USB-C for a direct, reliable connection.

The 1.2mm hot-swappable PCB means you can install your favorite switches without ever touching a soldering iron. The 5-pin sockets accept nearly any MX-style switch on the market, giving you endless possibilities to experiment with feel and sound. Also on board is full QMK and VIA support for deep customization of your layout and lighting. With both FR4 and PP plates included in the box, you have everything you need to start tuning the board’s flex and feel from the very first build.

Questions & Answers

What does 'barebone kit' mean?

A barebone kit includes the case, PCB, mounting plate, and all the necessary hardware for assembly. To complete the build, you will need to provide your own switches and keycaps.

What do I need to complete the build?

You will need a set of mechanical switches (any MX-style 3-pin or 5-pin will work) and a keycap set compatible with a 75% layout. A USB-C cable is also required for wired mode and for charging the battery.

What is a gasket mount?

A gasket mount is a system where the keyboard's plate is suspended between soft gaskets on the top and bottom case. This isolates the plate from the case, resulting in a softer typing feel and a cleaner, more muted sound profile compared to more rigid mounting styles.

Is the keyboard difficult to assemble?

The Love Letter 75 is designed to be user-friendly, especially with its ball catch assembly system which simplifies putting the case together. While some keyboard building experience is helpful, it's a great project for those looking to get into the custom keyboard hobby.
