Enjoy durability without cramping your style. Made from doubleshot PBT, these keycaps are thicker and sturdier, and won’t wear down to a shiny finish. They also showcase the sleekest, thinnest font ever seen on a PBT keycap for a clean, minimal aesthetic that will never fade. Superior PBT material for a textured finish that does not wear down to a shiny surface over time. Extra thick walls for solid keypresses and maximum durability. Unique doubleshot construction process for thin fonts that are backlight compatible and fade-resistant. Fits all Razer mechanical and optical keyboards, and any switch that uses a cross-shaped axis (eg: Cherry). Consisting of 120 keycaps and additional stabilizers for optical and mechanical keyboards, the Razer PBT Keycap Upgrade Set fits both Razer and standard 104/105 key US and UK layouts.
