Know before you buy
This is a 27-key add-on set designed to provide specific coverage for 40% mechanical keyboards. It includes a mix of primary brown keycaps with white legends and secondary black keycaps to complete your layout.
These keycaps are compatible with any keyboard using Cherry MX switches or MX-style clones. Since this is a specialized 40s kit, ensure your keyboard layout requires these specific key sizes before purchasing.
No, these keycaps are not designed for backlighting. The legends are opaque and will not allow light to shine through.
The Cherry profile is a popular choice for enthusiasts because of its sculpted, ergonomic shape. It is slightly shorter than the standard OEM profile, which many users find more comfortable for long typing sessions.
No, the legends are created using a double-shot manufacturing process. This means the characters are molded into the keycap itself rather than printed on top, ensuring they will never fade or wear away.
