These are Wuque Studio Aurora Series PCB mount, screw in stabilizers, and are designed to minimize the rattle as much as possible. The wires clip into the housing and fit into the sliders very snugly. As a result the wires are also less prone to popping out when changing keycaps.
Features:
- The housing design makes it very difficult for wires to pop out since they're installed from the bottom.
- There are ribs inside the housing to minimize lube from sticking to the stem, causing them to feel sluggish.
- Comes with PCB mounting pads and Teflon adhesive strips already cut to size to make holee modding easier.
