ANSI 104-key set printed in the ergonomic Workman layout.
Custom set from [WASD Keyboards(https://www.wasdkeyboards.com).
Color scheme designed for rapid, intuitive differentiation between keys frequently used while typing text.
Used, but very clean (see photo).
$10 OBO + shipping from Korea (probably 10-15 USD depending on location).
I switched to the Workman layout 2 years ago while using this set. Now that I touch type in Workman, I prefer heavier keycaps and so want to pass this set on to help other people make the switch.
