“If an Angel from Neon Genesis Evangelion became a peripheral, it would look exactly like this.”
KBDcraft is widely known for its “building-block” design philosophy. After a series of brick-inspired keyboards, the company is pushing the idea further—reworking earlier concepts to launch the #4 Shamshel. The result is a modular, LEGO-compatible, highly customizable building-block-style mouse.
The Meaning Behind the Name: The Arrival of the Fourth Angel
The name “Shamshel” is no coincidence. It is inspired by the Fourth Angel from the classic anime Neon Genesis Evangelion.
By pairing this cultural reference with the playfulness of brick building, KBDcraft turns the mouse from a simple peripheral into something more expressive—collectible, personal, and full of character.

Key Features of the Modular Mouse
Shamshel builds on KBDcraft’s signature design language while introducing several standout innovations:
1. Dual Switch System
Shamshel’s defining feature is its dual switch system.
Built around a custom internal structure, it supports both:
- Traditional mouse microswitches
- Low-profile mechanical keyboard switches
This gives users the freedom to choose between crisp click feedback and a more tactile mechanical feel, depending on preference.
2. Gearbox-Inspired Scroll Wheel
The scroll wheel uses a gearbox-style mechanism, offering:
- Precise control
- Clear tactile feedback
- A uniquely satisfying scrolling experience
Every scroll feels deliberate and engaging.

3. Unlimited Customization
Customization is where Shamshel truly stands out.
- Buttons feature a 3×3 stud-style brick layout
- Compatible with decorative keycaps
- Supports swappable LEGO-style round caps
This opens up endless visual combinations, turning the mouse into a fully personal design piece.

4. The 3D-Printed Precision Base: Where Engineering Meets Play
To bridge the gap between a "toy" and a "professional tool," KBDcraft introduces a custom 3D-printed optical base. This isn't just a frame; it’s a high-precision modular foundation that ensures:
- Structural stability
- Functional precision
- The joy of hands-on assembly

The Ultimate Toy for Brick Enthusiasts
As a brick-built mouse, Shamshel is fully compatible with LEGO elements.
“This isn’t just a mouse—it’s your imagination in disguise.” — Boyu
One standout detail is the LEGO minifigure holder on the palm rest.
You can place a favorite character on top to accompany you through daily digital work.
To make things even more fun, KBDcraft has created a minifigure inspired by Squid Game, adding personality and playful storytelling to the product.
