The SK621 is a truly portable keyboard with low profilemechanical switches. The 60% layout removes the numpad and dedicated nav keys to save space, but still packs all the signature Cooler Master features like On-the-Fly Controls, RGB lighting, and Hybrid Key Rollover. Cherry MX Low Profile RGB switches with reduced travel and actuation distance means you get all the precision and durability of a mechanical keyboard, but with the slim stylings of a minimalist, chiclet keyboard. Add in a refined brushed aluminum housing and Bluetooth wireless capability, and you have the ultimate on-the-go mechanical keyboard.
