Replacement lavender/blue 'Z', 'Q', 'S' and 'D' keys designed for Filco Majestouch and Tenkeyless French keyboards with Cherry switches, these keys will however fit all Cherry MX switches (they are slightly taller than the standard keys on a G80-3000 but have the same slope/angle to the key tops.)
Replacing the keys is easy, simply pull your old keys off, preferably with our key puller (see below), and push your new keys on.
