The base keycap set comes with everything you need if you use a US standard keyboard layout. Includes a couple of extra keycaps for better compatibility with multiple keyboard layouts. With this kit, you can get Noctua’s novelty keycap set along with the regular keycap set. This comes with Noctua’s logo and some fan-inspired designs are inprinted on the keycap. If you don’t like that base keycap set, you can also order customized keys for 10 key keyboards and many other combinations, including ISO UK keycaps, Colevrak keycaps, and Ortho Keycaps for more unique keyboards (and for keyboards designed for other countries). All the keybox sets come with the Noctua brown and white colors, both, while Noctua is not used to its own design language. Generally, the majority of the outer edge keys are made of brown. Noctua has a white color in all the keys in the middle. These keycaps fit into Cherry MX cherry switches, however they also can fit onto any clone you have.
