keep in mind that these fancy keycaps are only going to fit mechanical key switches, and we think it’s safe to say that most artisan ‘caps are designed for switches with a Cherry MX-type stem.
Sadly, you are not able to replace the switches either, as the K4V2 doesn’t support hot-swapping. The Cherry K4V2’s keycaps are made out of ABS plastic, which looks and feels very cheap.
The polycarbonate keycaps feature discreet cupping ... the KW X ULP is precise to type on and very durable. Cherry MX Ultra Low-Profile switches were developed and manufactured in Germany.
