Thanks to the ground-breaking technology used in making the injection molding mold of these keycaps, the Keytok CTRL Keycap is able to bring double-shot keycaps to a whole new level. We name these keycaps semi-transparent keycaps since one side of the keycap is made of colored, translucent, Poly-carbonate material, which enables the RGB light of your keyboard to go through the keycap, offering a nice lumination.
