Know before you buy
The KAT profile is a sculpted, spherical design that sits between the height of Cherry and SA profiles. It offers the ergonomic comfort of a Cherry profile with a wider, more modern surface area that feels very smooth under the fingertips.
The KAT Alpha v1.1 set is designed for keyboards using Cherry MX style switches, which includes the vast majority of mechanical keyboards on the market today. As long as your switches have the standard cross-shaped stem, these caps will fit.
These keycaps use dye-sublimated legends, meaning the ink is infused directly into the PBT plastic. This process ensures the characters will not fade or wear off, even with heavy, long-term use.
Yes, these are constructed from 1.65mm thick PBT plastic. This substantial thickness helps produce a deeper, more resonant sound profile compared to thinner, stock keycaps.
Because these are made from high-quality PBT plastic, they are significantly more resistant to developing the 'shine' that often occurs with cheaper ABS keycaps. The ultra-smooth finish is designed to maintain its matte appearance through extended typing sessions.
The choice depends on your keyboard's size and physical layout. We offer specific kits for Full Size, 40s, and Ergo layouts, so you should select the one that matches your board's bottom row configuration and special key requirements.
