ID42---The Cutest Layout in the Mechanical Keyboard market. Designed and manufactured by IDOBAO team. 40% layout, Three color with pre-build options to choose. Sturdy and heavy aluminum case to avoid moving on the desktop. Cozy feeling of touch, versatile color for mach with more options of keycaps. Compared with plastic frames, mechanical keyboard enthusiasts have often loved the aluminum body for its durability, As well as the distinct tactile feel and sound that no plastic body can reproduce. The frames were designed with a low profile for a streamlined look that complements any setup. The keyboard consists of upper and lower shell, PCB, PCB foam and Bottom Foam. In the new version, we upgraded the satbs to the screw in Stabilizer. PCB foam and Bottom Foam helps a lot for the sound and typing. The thick sound is the favorite of enthusiasts. The hot-swappable sockets are mounted on the PCB, so you can install or change the switches without soldering. The socket supports both 3 pin and 5 pin MX mechanical switches. The south-facing LED is designed to shine-through better from the all types of keycaps. It is more better than north facing design.
