CORSAIR improves the performance and durability of the keyboard with the help of PBT two-way keycaps. Each keycap is made with our special two-step molding process to ensure that the legend is always clear and easy to read. Each button is made of ultra-durable PBT and has double-thick walls, which can produce the most reliable and stable buttons. Backlight compatibility allows you to upgrade the keycaps without compromising the visual RGB effect. The complete 104/105 key set allows you to upgrade the complete keyboard. These keycaps are compatible with most CORSAIR mechanical keyboards and CHERRY switches.
