Craftsmanship and Design

This number pad exemplifies modern design with its ultra-slim profile, achieved through the use of Keychron’s Low-Profile 2.0 Mechanical Switches, which are 33% slimmer than standard switches. The device is constructed with a blend of ABS and aluminum, resulting in a lightweight yet sturdy frame that resists flex and daily wear. The ANSI layout ensures compatibility with standard keycap sets and familiar ergonomics, while the inclusion of a macro column and a tactile rotary knob adds both utility and a distinctive visual element. The double-shot PBT keycaps are engineered for durability, resisting shine and wear over time, and provide a satisfying texture for extended typing sessions. Redesigned stabilizers minimize key wobble on larger keys, ensuring a consistent and reliable feel. The overall build quality is tailored for both portability and longevity, making it suitable for both desktop and mobile workspaces.
