Know before you buy
These keycaps are designed for Cherry MX style mechanical switches, which includes most standard mechanical keyboard switches on the market today.
No, these keycaps are made from opaque doubleshot ABS plastic and are not designed to be shine-through. Your keyboard's backlighting will not be visible through the legends.
The Cherry profile is widely considered the industry standard for comfort. It features a sculpted, ergonomic shape that sits lower than the OEM profile, making it a favorite for long typing sessions.
The 1.5mm thickness provides a solid, premium feel and a deeper sound profile when typing. Because they are doubleshot, the legends are molded into the plastic itself, ensuring they will never fade or wear off over time.
The Base kit covers most standard keyboard layouts. If you have a non-standard layout, such as one with unique bottom row sizes or specific aesthetic preferences like the Hangul or Stripes options, you may need to purchase additional kits to ensure full compatibility.
