Know before you buy
These keycaps are designed for Cherry MX style switches and support conventional ANSI layouts. With 136 keys included, they provide broad compatibility for most standard mechanical keyboard sizes.
PBT plastic is denser and more durable than ABS, offering a slightly textured surface that resists the oily shine that develops over time. The 1.75mm thickness also contributes to a deeper, more solid sound profile when typing.
No, the legends are created using a 5-sided dye-sublimation process. This infuses the ink directly into the plastic, making them highly resistant to fading or wearing off, even with frequent typing.
The Cherry profile is a popular, standard height that features a sculpted, ergonomic shape. It is generally considered comfortable for both gaming and long typing sessions due to its familiar, tiered layout.
The set is specifically optimized for conventional ANSI layouts. If your keyboard uses non-standard bottom row sizes or unique key widths, you may find that some keys do not fit perfectly.
