Enhanced Design & Materials: The GMMK PROs body is CNC machined from solid aluminum giving it substantial weight and unrivaled durability compared to plastic alternatives. Anodization gives the bodys surface high scratch resistance and a satin-like feel. Beneath the boards keys is an aluminum plate that creates a solid and consistent typing feel while also safeguarding internal components from damage or debris. | 5-Pin Hotswap Design: Personalize the boards typing experience by plugging in your favorite 3 or 5-pin MX mechanical switches from Glorious Kailh Gateron Cherry and more. No soldering required. The included switch puller makes replacing switches quick and hassle-free. | Fully Customizable Appearance: The GMMK PROs included top frame rotary knob and cable are easily replaceable with colorful alternatives from Glorious specially engineered for a perfect fit. This keyboard is designed to be redesigned. | Incredible Control: For even further modification of the keyboard experience the GMMK PROs pre-installed aluminum switch plate can be swapped out with alternative styles from Glorious. Swap in the Brass plate for a firmer typing feel and brighter sound. Or the Polycarbonate plate for a softer feel and deeper sound. Foam inside the case can also be added or removed to adjust the acoustic profile. | Included Components: GMMK PRO 75% Barebone Frame 2M Black Braided USB-C Cable Switch Puller & Keycap puller
