Based on the profile from the iconic IBM® beamspring terminals of the 1970s, this custom set is fully sculpted from dye-sublimated PBT in Hi-Profile. What's Hi-Profile, you ask? Many computer terminals of old were constructed with a slanted switch layout from front to back. Because of that slant, the keycaps sat at an angle atop the switches, too. This set is a reimagination of that unique slanted build, but optimized for modern keyboards. Thanks to some significant design work from Matt3o, 3D modeling, and a whole lot of elbow grease, we're proud to bring these innovative caps back for a second run. Here, we’re offering kits specifically for our CTRL, ALT, SHIFT, Preonic, and Planck keyboards—or other, similar boards, if they’re compatible.
