The Lily58 Comptroller keyboard case is made from real walnut. After laser cutting, the plates are treated with two coats of linseed oil over the course of five to six days. Each case includes screws, standoffs, and clear acrylic OLED covers. Please specify in the comments section if gray tinted OLED covers are preferred.
Information about the Lily58 keyboard along with the source files from the designer can be found on the Lily58 Github repository. QMK key mappings and firmware can be found here.
