Black Windowed Lamp R4 Keycap for MX Compatible Switches

These stark and elegant Black Windowed Lamp R4 Keycaps are made of opaque black plastic with a small cutout in the south-center edge that wraps around the top and bottom. The cut-out has a clear plastic window to allow an LED installed under the switch to glow through. They add a bit of the je ne sais quoi to your keeb or macropad build and are somewhat rare to find.
