This is an original Kickstarter-backed Keytron K1 low-profile mechanical keyboard. Includes original Keytron branding, as the company had to change its name to Keychron while this keyboard was in production. Keychron became one of the leaders in the mechanical keyboard industry thanks to this keyboard and the rest of that original kickstarter campaign. Now you can own a piece of computer hardware history!

This 100% layout uses low-profile mechanical switches, RGB backlighting, and multiple built-in profiles. The keycaps have macOS markings.

This keyboard has profile switches to switch between macOS and Windows/Linux and between wired and wireless modes. Wireless mode is via Bluetooth.

This keyboard was a daily driver for a few years of a gamer/programmer so it has wear on the keycaps where you would expect. It's super noticeable on the ‘a’ and ‘s’ keys. See pictures.

It's been sitting in a closet for a few years. Presumably, it still works but hasn't been plugged in.
