STURDY MILLENNIUM-OLD MORTISE-TENON TECHNOLOGY: Inspired by the mortise and tenon technique of woodworking, we designed the joints of the KiiBoom Moonshadow 81 to be firmly connected at right angles. 75% HOT-SWAPPABLE LAYOUT: The 75% keyboard layout is the perfect balance between functionality and portability. The Moonshadow 81 features hot-swappable switches. Mechanical switches come in various tactile and auditory styles. PREMIUM ALUMINUM CASE AND FRAME: Aluminum dissipates heat faster than other metals. It means that you can work with this type of keyboard case anywhere. We provide PC (Polycarbonate) plates for gasket-mounted keyboards. PC is extremely flexible, providing a slightly cushioned typing experience and an incredible typing sound. QMK & VIA SUPPORT: QMK/VIA allows users to intuitively remap any key on the keyboard and create a multitude of macro commands, shortcuts, or key combinations for your keyboard.
