The SK621 60% mechanical keyboard features brand new Cherry MX Low Profile RGB switches and hybrid connectivity (wired & BT) in a durable, stylish portable format that puts all other slim keyboards to shame. 

This is a truly portable, fully mechanical gaming and creative professional keyboard with Cherry MX low profile RGB switches. The portable 60% keyboard layout allows for a compact, slim form-factor, while keeping all the useful features of a full-sized keyboard. SK621 has all the standard Cooler Master features like On-the-Fly Controls and Hybrid Key Rollover (In Wired Mode). Most importantly, it features the new Cherry MX Low Profile RGB switches - a fully mechanical switch slim enough to fit inside a chiclet keyboard. As a result, you get all the precision and durability of a mechanical keyboard with the slim stylings of a minimalist, chiclet keyboard. Add in a refined brushed aluminum housing and Bluetooth 4.0 connectivity, and you have a proper on-the-go mechanical keyboard for both work and play.

The SK621 is intended primarily for creative professionals seeking a better slim keyboard that doesn’t sacrifice aesthetics for functionality. Although we are already getting great reception from gamers, we believe this will be incredibly popular with creative professionals and casual mechanical keyboard enthusiasts — primarily those who are heavily integrated into an Apple-based ecosystem. Many have been clamoring for a low-profile, chiclet-style keyboard that not only feels good to use, but also looks good on their desktop next to their sleek Apple devices. The SK621 meets these needs with:

1. New Tech: A combination of Cherry MX Low Profile RGB switches and signature Cooler Master features appeals to gamers, mechanical keyboard enthusiasts, and creative pros.
2. Design: The brushed aluminum top plate, contoured slim keycaps, and minimalist design is a striking difference from other mechanical keyboards, appealing to those who prefer compact, low-profile chiclet-style keyboards.
3. On-The-Fly Control and Software: Core gamers have the ability to customize macros, profiles, and lighting schemes easily.
4. Wireless Keyboard Capability: The wireless hybrid design means you can either choose a corded or cordless set up based on your own preferences.
5. Large-Capacity Rechargeable Battery: An internal battery is easily charged with the USB-C cable.

Designed with simple good looks and minimalism in mind, the SK621 features a brushed aluminum top plate, contoured keycaps and a 60% format layout built with all of the essentials. New Cherry MX Low Profile RGB switches and contoured keycaps allow for a stylish profile. A combo of durability, portability, and incredible responsiveness, this keyboard is the ultimate portable mechanical keyboard for creative professionals and gamers alike. The floating keycaps retain the flat, square shape of a chiclet-style keyboard, but we’ve added a slight contour to the middle of the cap to improve comfort and accuracy during extended use without the need for a wrist rest or elevated feet. The flat layout and slight contoured keycaps results in a better ergonomic experience when on the go.

SK621 gives you the option of both wired and wireless function with Bluetooth 4.0. Under Bluetooth mode, SK621 allows users to save pairings for up to 3 different devices for easy switching on the fly. The removable Type-C cable and wireless hybrid design means you can either choose a corded or cordless set up based on your own preferences.

Told ya, it's small, slim and low profile.
