CoolKiller Polar Theme CSA Profile Keycaps Set

The CSA V3 profile is a sculpted, spherical keycap shape that sits somewhere between the classic OEM and SA profiles. It offers a taller, more rounded surface area that cradles your fingertips, providing a tactile and comfortable typing experience that many find more ergonomic than standard flat profiles.

These keycaps are designed for compatibility with any keyboard using Cherry MX style switches, which includes the vast majority of mechanical keyboards on the market. With 113 keys included, the set covers standard layouts as well as many popular compact configurations.

Dye-sublimated PBT is highly resistant to the shine and wear that typically develops on cheaper ABS plastic keycaps over time. Because the ink is infused directly into the plastic, the legends will not fade or rub off, ensuring the set maintains its crisp look even with heavy daily use.

The 113-key count provides broad coverage for most standard layouts, but it is best to compare your keyboard's bottom row layout against the set's included keys. If you have a highly unconventional layout, such as those found on some specialized ergonomic or ultra-compact boards, you may find a few keys do not match perfectly.

No, these keycaps are opaque and do not feature shine-through legends for RGB backlighting. The aesthetic focus is on the vibrant, themed design, so while your keyboard's light will glow from underneath the keys, the letters themselves will not illuminate.
