The wireless Matias USB-C Aluminum Keyboard is a full-sized scissor-switch keyboard made of anodized aluminum in Silver, Space Gray, or Black. The battery lasts up to three years before needing to be recharged. It features our patented USB-C Nano Receiver, the world's smallest wireless receiver for USB-C. Simply plug the receiver into your computer, and your keyboard will work instantly. Thanks to the AES-128-bit encryption of the wireless transmission between the keyboard and receiver, the keyboard is also suitable for high-security corporate or government environments.
