note: This is neither a keyboard nor a set of keycaps, just a single keycap. The lowest position of the key cap height is about 0.9mm, which is close to the height of the cherry R4 keycap, and is about 0.11mm after the surface solid group. It is close to the OEMR4 keycap height; it is recommended to install in the ESC, F zone and the main key digit zone. Each DIY keycap has a beautiful gift box.
