Ultra-low-profile MX keycaps
SLK is a uniform profile keycap delivering a new ultra-low-profile option for MX-style switches with no compromises. The keycap's spherical top surface provides a "cuppy" feel, reminiscent of arcade machine pushbuttons. It features a thick PBT construction, with an extended skirt below the typical bottom of an MX keycap to provide a deeper sound.
Synth Labs originally designed the SLK keycaps for a rythm game controller, that idea quickly expanded into a full-on keycaps set.
