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.

Snaps onto any Cherry MX or compatible switch. It's R4 profile so will work nicely as a stand-alone key or at the top row of your keyboards.

Note: This product is a single keycap, and key switches are not included!
