20% Mechanical Hot-Swap Barebones Kit

As a great companion to the predecessor - CK820, this 20% keyboard of CK210 will give you a few extra keys for coding, gaming or just for convenience. You can put this side-to-side with the CK820 or use it as a stand-alone mini pad. No matter what you're looking for, this numpad can meet all your needs with this fully programmable and hot-swappable keyboard.

Solid Aluminum CNC Case

Only the best materials are chosen for this solid and sturdy keyboard. The Aluminum Alloy is known for its hardness and the strong support it provides for the keyboard. It is extremely hard to break or dismantle some thing made of steel. And on top of that, this pad also applied one of Mxrskey's Special, the plate-mounted stabilizers, for extra support on switches, ensuring a disturb-less typing.

Three Connectivity: Bluetooth/2.4Ghz/Type-C

Offering wired stability and wireless freedom at once, the CK210 support three types of connection to meet your changing needs in various scenarios and situations. The type-C port is tight and firm for stable connection, while the Bluetooth 5.0 and 2.4GHz wireless make it easy to control your device in a distance without any scarifies at speed and stability.

Great Sound with Gasket Mount

Just like the Mxrskey CK820, the CK210 is a Gasket Mount Board with two layers of sound-absorbing foam and glass-epoxy ENi/IAu supporting board. The foams are great in noise-canceling to eliminate unwanted noise while the Fr4 board provides clear and crispy clicking sound for greater enjoyment.

Programmable RGB & South-facing LEDs

Flashy RGB with awesome light effects and patterns is a great highlight that this kit features. The south-facing LEDs avoid interference with cherry-profile keycaps. And if the dozens of default light patterns are not enough, this kit also supports customization with a specially-made driver.
