Compatible with Cherry MX switches, this set comes with 117 keys in the Cherry profile made with lightly textured PBT plastic to give the best touch type experience. To accommodate some of the different bottom row keyboard layouts this set includes a 7u, 6.25u, and 6u space bar as well as modifier keys in 1.25u and 1.5u. These are blank keycaps and come legend free which will help increase your typing speed while also removing any concern you might have of fading letters.
