Ahh, custom keycaps. Irresistible. They came from YUZU Custom Keycaps. The original set were black which I didn't like when it was dark in the room. I couldn't find perfect symbols for all the 'odd' keys but I'm pretty happy with how it turned out. The keyboard is a UHK 60 from Ultimate Hacking Keyboard which I've been using since 2019. SpaceMouse in the middle and gel wrist supports for both hands.
